My wife and I just returned from our honeymoon at the Grand Wailea, and I will list the very good, the bad ( not much) and everything in between. From the moment you walk in, the hotel itself will blow you away with how breathtaking it is. We visited the Four Seasons, and the white hotel next door to the Four Seasons ( cant think of the name ) , and trust me, although the Four Seasons is nothing to sneeze at, its not nearly as dramatic, and open and large as the Grand W. Remember the movie phrase, " You had me at hello"? That's kind of how you feel when you walk through the large lobby of the GW. Regarding our room , we had an ocean view room on the 8th floor, which was ready for us, with a warm bath, with flowers floating on top.. A nice honeymoon touch that we didn't expect - On a one to ten rating regarding the room being perfectly clean, I would give it an 8. A large hand print over the headboard that you could see in certain day light knocked down the rating. The bed was comfy, had a flat screen TV, and the bathroom was large with a tub and shower. The balcony was pretty big too which had a large table , two chairs and enough room where you can stow your suitcases. The pool situation at the GW is crazy -insane- nice. ( And probably 3 times larger than the FS hotel. They have an adult pool and a kiddie area with water slides. The overall grounds at the GW are very well maintained. Spend the time yourself and look online at the pictures so you make an informed decision. You'll see what I mean.
The gym at the GW is two levels overall and rates pretty highly among hotels. I generally stay at 4 star hotels and this is one of the best I have come across. They have very top notch new equipment with a decent amount of free weights too. Don't be surprised to run into a few celebrities. We did. They offer yoga classes on the beach, boot camp, spin you name it. The SPA itself is huge and my wife and I did a couples massage. Personally I'm not that big of a spa person but it's as nice as I've seen, and of course the price tag comes along with that. They have like 5 different types of bath tubs to soak in Japanese style, hot tubs, 2 steam rooms, and like most places every treatment you can possibly imagine. Heads up look for a pretty decent discount coupon on your inboard flight magazine. Unfortunately we found it on the way home. A few things that I thought could be better. The restaurants closed mostly at 9pm. The main bar closed at 11ish. Overall if this place had any downside, the dining experiences we enjoyed the most were located off property. The best the GW has to offer is the Humuhumunukunukuapua'a. I wouldn't say any of their restaurants are terrible but for the money certainly not stellar. The place to be dining wise, is outside under that stars at Ferrars( Four Seasons), Tommy Bahamas, two minutes away at the shops at GW and of course an old favorite Ruth Chris. All not cheap but all very very good. We didn't get to try Spago's but heard great things there too. For the area that the GW is situated, being young and wanting to party a bit, the downfall is pretty much the entire town closes early. Certainly the bars at the GW do. Mulligan's a bar around 3 miles away located at a golf course ( go figure ) is open the latest and seems to have a local theme. We also suggest hitting the local Kmart or Walmart, twenty minute drive and loading up on a cheap cooler and beer and some snacks. This will save some money because the drinks are $$$$$. Other misc. info. Room service food is consistent with what I said about the restaurants. Make sure to put the do not disturb sign on your door. They are very consistent on knocking on your door to clean your room. Wi-Fi is not available in your hotel room but it's free in the lobby and the Napua towers lobby. This could certainly be improved. It is 2009? The beach is large and nice, and chairs and umbrella's are free. Also they don't allow you to swim in the hot tub or pool very late. Security guards get notified by cameras if you try. We did several times. So like anything else in Maui, this place is very expensive, very romantic, and my opinion VERY worth it if you can afford it. OOPS I almost forget. The staff that we came across were great. Hope this helps someone.
