Hi Stephan,
Thank you so much for visiting the Disney Parks Moms Panel with your question.
Disney's Beach Club Villas is such a lovely resort! The quaint beach theme is charming, and the ability to walk to Epcot in just a few minutes is wonderful! As you pointed out,
Stormalong Bay pool area has so much to do, including a lazy river to float on in inner tubes.
When my family stayed at this resort last fall, we found that inner tubes were always floating in the lazy river and were available for guests to use. I called and checked with both Disney Vacation Club Member Services and Disney's Beach Club Villas, and cast members confirmed that this is the system now. Inner tubes are placed in the lazy river and guests can use them at no charge.
I do suggest that you carry your Disney Vacation Club Member Card as well as your photo ID with you around Walt Disney World. I have gotten in the habit of asking at every location where I make a purchase at Walt Disney World whether they offer a Disney Vacation Club member discount. There are so many places that do! Please do note that discounts can change.
I hope that this information is helpful for you, Stephan. Please do let us know if you have any further questions.
