Hello, Yvette! It sounds like you have a fun decision to make. Disney's Beach Club Resort and Disney's BoardWalk Inn are both in the Deluxe Resort category. Let's take a moment to consider the differences between these two awesome Disney Resort hotels:
Disney's Beach Club Resort is within walking distance to Epcot and a short boat ride away from Disney's Hollywood Studios. You and your family can enjoy a nice character meal at Cape May Cafe without having to leave the property. It is also the home of Stormalong Bay, an amazing three-acre water play area. Children age 3-12 can enjoy the Sandcastle Club while you walk over to Epcot for an evening meal. You have had a great experience there on a previous visit, so you know what to expect from this property.
Disney's BoardWalk Inn is located right on Disney's BoardWalk, and is a particularly convenient walk to Epcot or Disney's Hollywood Studios. There are no supervised children's activity centers at Disney's BoardWalk Inn, but you can enjoy private in-room babysitting services for an additional fee. It's a new-to-you property, and you mentioned that you can save 30 percent on the regular room rate with a promotion that you have been offered.
This decision will really come down to what experiences are most important to you. My family and I do not spend a lot of time at the pools on our trips, but we do spend a lot of time exploring Epcot and Disney's Hollywood Studios. I might choose Disney's BoardWalk Inn for my next vacation because of those two factors. These are both wonderful properties, and either way, you cannot go wrong!
