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.
