If you have young kids, I don't know why you'd go anywhere else. We stayed for seven days and had the best time. We bought the gold meal plan, which gave us three meals per day. You can use the plan in any restaurant but we only used the main dining room where they had a great buffet with something for everyone, including picky kids. I usually get sick of dining in restaurants while travelling because I get tired of the whole procedure of ordering, waiting, entertaining my child. But, with the buffet you can eat and run, if you want, or linger when you are all in the mood.
The water park was super relaxing and entertaining for the whole family. What was so great was they had plenty of equipment and plenty of space, so you could always do what you wanted, when you wanted and you could always get equipment: inner tubes, snorkel masks, etc. We heard from the chef that they serve 700 breakfasts everyday, so the place is pretty crowded but you'd never know it because the grounds are so spacious and the activity options are diverse, so people are spread out. You never feel agitated by crowds. I guess the only place you really see a crowd is if you go to the dining room at peak hours. Around the resort, you can always get a chaise lounge and towels are abundant. There are free water stations all over the place, so you don't need to buy water and the hotel water is filtered, so it tastes fine.
The staff is super perky, friendly, and helpful and after two hours in kids club, they all knew my daughter and said hello to her by name around the resort, so she felt like a celebrity. My daughter went to kids' club two and a half hours per day which gave my husband and I time together after a morning of family activities, but some kids went from 9:00-5:00 -- they can either go mornings, afternoons, or all day. The kids' club is included in the price of the resort and, in the afternoon, they also provide a snack. The "clubmates" (kids' club leaders) are skilled at dealing with kids from all languages and cultures and they do fun games and activities all the kids can figure out, so don't worry if your child doesn't speak English. Some of the clubmates speak other languages, as well.
At 8:30 every night, there is some kind of show or entertainment for the whole family and the pools are open til 10:00. The lifeguards are well trained and keep a keen eye on the pool, so your child will be safe. They don't allow rough play/ dunking so if your kid is out sight, you can still feel that they will be safe in the pool. Also, there are life jackets all over the place for any kid or adult who is not confident in the water and they will require young kids who are swimming alone, and not strong swimmers, to use them.
The resort even provides clean socks and sneakers to borrow if you decide to play tennis or take a tennis lesson. The shoes and socks looked new and fresh and I felt fine using them. The tennis coach was actually a very good teacher -- I was impressed by how well he taught, explained things, and dealt with three different adults at three different levels at the same time.
We had so much fun, we never left the resort the whole week. We arrived in the middle of the night and were picked up by the hotel van, so we did not get to see the island and when we left I told the family to look around as that was our only chance to see the island. We were not interested in showing our daughter war memorials or going scuba diving, so we did not feel we were missing anything. We found our room as good as any other place we've stayed. Everything was super clean and beds were comfy. Wood floors meant we didn't worry about sand and they got cleaned everyday. The halls are a bit noisy -- you can hear through the door -- and everyone (ourselves included) seemed to turn in to teenagers and be up late at night and sleep late in the morning.
Recommendations: Bring at least two swimsuits and coverups per person, because that is all you will wear the whole week. And also two pairs of shoes that you don't mind getting wet because you will be shoving your wet feet into them throughout the day. You can not wear wet clothes in the dining room, so be prepared to either be dry or go change before eating. There is a nice locker room/shower room near the pool, if you don't want to go back to your room to change. I would also recommend buying or bringing both water shoes and UV swim shirts, both of which they sell in the boutique for an average/fair price. I bought a UV shirt but did not buy the shoes and, after a week of being in the water, the soles of our feet were sore and I wish I'd bought some shoes. There are no books or magazines for sale in the hotel or in the convenience store across the street, nor in the airport, so bring your own. There is a small lending library of books and magazines left behind by other guests, but not much for English readers. The air temperature in Saipan is a near constant 82 F. So, you can step out of the ocean or pool and not feel the slightest bit cold. You will need nothing warmer than a long sleeved tee-shirt. Even when it rained, everyone kept right on swimming or playing, because the air was still warm. We travel two or three times per year as a family and this was our best vacation by far because the resort provided something for everyone - not just for kids - not just for adults - so we were ALL satisfied, rested, relaxed, well fed, and sufficiently entertained. As a parent, I got a break from parenting duties, but didn't feel like I was neglecting my child because she was so happy. It was a true vacation for us all and none of us wanted to leave!
