Pool WAI One-Day Model Course | How to Spend the Day from Afternoon to Night

To make the most of Pool WAI from morning to night, the key is knowing how to move around by time of day.
Here is a model course for enjoying the day efficiently.

Morning (Opening–11:00 am)
Prioritize the slides and popular areas before it gets crowded. Giant Sky River is especially best in the morning.
Midday (11:00 am–3:00 pm)
This is the most crowded time of day. We recommend relaxing in the lazy river or wave pool and taking a break in the food area. You can also watch stage events and shows.
Late Afternoon (3:00 pm–6:00 pm)
This is when the crowds gradually begin to ease. It is a good chance to enjoy the slides and active attractions again.

By entering in the morning right after opening or after 3:00 pm, you can enjoy the attractions relatively smoothly.

3. Protect Against Sunburn and Heatstroke, and Reserve Paid Seats Early

Because you will be spending a long time under the hot sun, heat protection such as sunscreen, a hat, and a rash guard is essential.
