Welcome to the Disney Parks Moms Panel, James!
I, too, enjoy my time soaking in a hot tub while vacationing. Their is also something a little more magical about enjoying them at a Walt Disney World Resort hotel. Disney's Coronado Springs Resort's main pool,
The Dig Site, boosts the largest hot tub on-property!
Hours of operation can vary significantly by season, but for your late-January visit, you can expect pool hours to be approximately 10am-8pm; lifeguards will also be on-duty between these hours (main pool only).
I hope this helps in your planning, James! Please let me know if you should have any additional questions regarding your stay at this unique, Spanish-inspired resort.
