I booked this place to bring a few preteens for a sleepover. The kids were oblivious to the things that an adult would notice. Therefore, they had a blast. However, there were areas that they would not allow them (12 yr old) as they were too old--like under the huge and exciting water bucket that pours every few minutes, and areas that they would not allow them as they were too young-hot tub-so that was limiting.
The hotel was old, tattered, had extreme signs of wear and tear. Blistering paint, peeling wallpaper, old and broken furniture in the room. The suite we booked consisted of a King size bed (without a door) that lead into a 'bunkbed" Jr suite. The bunks were very small for preteen girls and really were meant for preschoolers (clearance space between the top and bottom bunk), which was attached to a very meager kitchen area. The floor had a big sticky circle of someone else's spill or whatever that I had to clean. The rooms were supposed to sleep 8, which obviously (2 sets of bunks and one king) slept only 6. I nicely informed the front desk and they gave us the adjoining room (a 3rd room) for free. That helped, as there was only one bathroom to begin with. It overlooked the waterpark which was ok, but made the room loud and boiing hot--the waterpark area is blazing hot to anyone staying poolside to read or watch kids.

The little bar/pizza area was manned by a guy who continuously coughed and wiped his face and back of his neck with a bar towel. I was grossed out by that. The food was good, however--so no complaints there. He was very pleasant, but I suspect not as clean as I would have liked.

Thought the manager handled the bedroom problem nicely.

I felt there was some rough characters staying there due to being close to the expressway, but there was no trouble. There was security guy who walked around all of the time and kept a close eye on things. The pool staff seemed very attentive too.

Room itself was adequately clean but seemed like it really needed a makeover. King bed very comfortable.

Won't be going back!

Wow, Sorry to hear about other experiences. We had a fantastic time and the staff was FANTASTIC, too. I say this because my 2 year old daughter threw the WORST tantrum in history when it was time to leave the water park, and 2 staff members came to help me out. I was stuck in the locker room alone trying to control a screaming toddler who was over-tired but wanted more water park. I was at my wit's end and Embarrassed. My daughter was screaming non-stop and trying to run back into the water park for over 30 minutes. I started to cry myself because I was so overwhelmed. I'd never seen my kid like that before. Staff members came around to help me hold her down and get half-dressed. A very nice employee gave my daughter some French Fries and EVEN OFFERED TO GIVE ME A FREE RETURN PASS FOR ANOTHER DAY. I declined the offer, but I thought that was SO NICE. THAT IS GREAT Customer Service!
The lifeguards at the water park were very attentive and helpful. One young man stayed close to my daughter at all times at the bottom of the kid's slide while I stood at the top. My daughter is a quick one and really loves water. A staff member also gave me a money saving tip on the restaurant-should I decide to eat there. I appreciated that information. Kids under 12 INSIDE the restaurant eat free! Overall, I thought the staff and facilities were GREAT. They have a very nice Toddler section for the little ones. We live close-by so we only got a day pass this visit, but have stayed in the hotel rooms years ago, ( before the water park was built). We never had any problem. Our Family & Friends always like staying at this hotel close to our home. My day-pass visiting experience was SO GOOD, we will definitely book an overnight stay soon. The other visitors and overnight guests seemed to be enjoying their stays, too. I guess I can see it being unsatisfactory if the place is very crowded-but on an average Friday- I had NO COMPLAINTS. Plenty of staff and smiling faces. The water park is not as big as a Wisconsin Dells water park, but it's not TINY. Keep in mind, some people ONLY visit TripAdvisor to complain. When they have a nice stay, they forget to leave a review. I HIGHLY RECOMMEND THIS LOCATION!!

We got a day pass to Mayan Adventure on Christmas Eve. We stayed at the Elmhurst Holiday Inn for one night shortly after the water attraction opened, and so this was our second visit.
Unfortunately the water park is in need of maintenance, it showed age after one year. There was a ring of dirt all around the pool ledge that was unsightly. The pool water was as warm as a bathtub, but the tot's play area had just had the water changed and was so cold that nobody could play in it, it was like cold water from your hose in December. I feel sorry for the people who showed up with little children.
The main pool has three basketball hoops so that there was ALWAYS several basketball games going on. Did they supply soft balls to play with so that nobody just playing in the pool would get hurt by an errant ball? Nope, six regulation basketballs were being thrown around by the bigger, unsupervised kids and I saw a three year old take one full in the face. There were few places to escape other than a couple little coves, so the main pool was more or less off limits too. Also the basketball hoops are getting rusty and nasty looking. At the arcade, it seemed that 7 or 8 of the games were out of order.
Positive points: staff is polite and professional. Food service seemed good, the changing room was clean.
I don't think we'll be going back, it was quite mediocre.

Recently I came to the Holiday Inn as an inexpensive and fun way to spend a weekend with my family. My husband and our 4 year old daughter and 10 year old son were just thrilled!! They had so many activities for them to choose from including an area just for my youngest to play in and waterslides that my son just couldn't get enough of! It wasn't all fun just for them though! They have a great restaurant where we ate, drank cocktails, and watched TV. Our waitress was excellent! The BEST service I have ever had in a hotel (and I travel a lot!) If anyone is looking for a hotel in the Chicagoland area that is kid friendly this is IT! Have FUN!!!!!
