Great waterpark, although not as big as the GWL at Niagara Falls. LOTS of life-guards around, indoor & outdoor hot-tub, wavepool, waterslides, etc. Beds were very comfortable. We pre-purchased the breakfast option and it was worth it. Dinner prices were a bit high so we went to nearby Country Cousins (see restaurant review for that).

Thanks to Living Social I was able to get a suite at a very cheap price. But really considering the room includes the use of the indoor waterpark it wasn't really that bad even at the regular price. In general the whole place was clean, friendly staff, excellent food availability capped by Starbucks on site. Paying full price would be worth it. My only negative about this is the bed is very soft and uncomfortable. We sank towards the middle and had back aches the next day. We stayed on the bear suite which had a masters bedroom with a king bed, another bedroom with 2 queen beds and a living room with a queen sofabed. The room had a jacuzzi tub in the masters and a walk in shower for the rest out by the living room. TV sets in both rooms and living room, a small fridge, coffee maker and a microwave. I would definitely recommend this place.

The kids always get excited whenever they see the commercials on television, especially in the winter. Definitely a great place to bring your young ones. It's sort of a cross between a theme park, a water park, and Harry Potter. I don't think it's a place to stay more than 1 night, and if you do it right, you can spend 2 full days in the water park. Definitely no more than 2 nights max. We splurged on the room (Kids Cabin), which was smaller than the pictures online, but works really well if you have 3 kids with you since they have their own room with 1 bed and 1 bunk bed. Ask for a room opposite the I-5 and higher floors if possible for better sound proofing. The real reason you go here is for the water park. There are 4 "adult" slides (long lines), 2 "kid" slides, water playgrounds for both big (6+) and little kids (3+), large pool and a wave pool. Definitely go during the winter time since it's over 80 degrees and humid, and the water is warm. We bought the breakfast buffet as part of our reservation, which was worth it since checkout is at 11am sharp (no late checkouts). The breakfast was marginal but effective. Don't expect good service since there aren't a lot of waitresses and everyone eats at the same time... I would however highly recommend that as soon as you wake up on the day you check out, bring your bags to your vehicle right away since everyone (including housekeeping) will rush the elevators around 11am, and you will find yourself waiting for an empty elevator... If you can go there during the weekday you will probably have the place to yourself since the weekend was a zoo. As for dinner, we didn't try the hotel restaurant, but went to Centralia (1 exit down) and ate Mexican food at Casa Ramos which was actually decent. I did see a few people taking food/pizza to their rooms... You should skip Burgerville in Centralia altogether, unless you like McDonalds. Other things to do in town - not much - maybe shop at the outlet mall...maybe.

We went there on Christmas eve thinking it would be a quieter time and boy, I couldn't believe how many people had the same idea! It was only slightly less crowded than regular weekend, judging from my previous visit, but it was a very enjoyable stay nonetheless. We checked in at 3pm, got our room on the first floor, and went to the pool right away.
The first floor room got us worried, but there was no reason to. It was great, and to our surprise the first floor room had a very high ceiling, much more than the usual 9-10 feet. I don't know why the first floor has much higher ceiling, but it does, and it makes the room feel much more spacious. Awesome. I would definitely pick the first floor again the next time.
The pool itself is awesome of course. My kids' favorite is the wave pool where they spent much of our time there.
Yes, we definitely would visit around holiday times again :)
