Our family has gone to Splash Lagoon many many times. We love it. Have never been to GWL. First there is NO wave pool at Splash. The park has approximately 5-6 large slides. Some are more daring then others but all our fun. There is 3 hot tubs, 2 family 1 adult. There is an interactive water area for babies/toddlers, another for younger children and a pool that has basketball set up for older kids. We enjoy everything in the actual water area. Also there is a lazy river...
About the whole experience..
There are 3 hotels that are actually attached to the water park. This is definetely a must. We have stayed at all three. We prefer the Residence Inn. Comfort Inn rooms are located next to the Thruway and have a higher noise level. This is the cheapest of the hotels but also the loudest. It has a swimming pool and so does the Residence Inn. The Holiday Inn never did it for us.. No extra swimming pool and more of a business person's place. All hotels offer free breakfast.. All very good. Residence Inn has some free dinners during the week. Never had a dirty room...
Back to the Splash.. Upper floor has a great game room that we have spent hours in also if this is your thing. I usually designate $100.00 just for this. There is a gift shop, small bar, and activity rooms. They offer games like bingo, air hockey tournaments etc. You have specific times for these but most are free. If you do the crafts there is usually a small charge.
FOOD... The food inside the park is well, park food and its located in a very wet area. We go to the Boston's outside if we don't want to drive and if you don't mind leaving there is every food place you can think of down Peach Street. Peach Street also has every store you can think of and a mall. Outside of the area is Presque Isle Park (beach)..
www.presqueisle.org. Depends on summer or winter visit.
If you have any other questions or want to see pics let me know...
Hope you enjoy your vacation no matter where you go..
