Hi Toni!
No worries, no need to second guess your decision. I toured the 2-Bedroom villas for Disney's Bay Lake Tower and was really, really impressed! I bet the kids will really dig the futuristic feel of the resort, and it will be pretty cool to tell their friends they were one of the first guests to stay at Disney's newest resort.
The location of the resort is superb! You will have great access to the theme parks and recreational activities. This will come in handy for hopping back to the resort for a swim during the hottest parts of the day. In the evening, you'll be able to view the Electrical Water Pageant each night (weather permitting) on Bay Lake.
There will be plenty to do at the resort itself, such as swimming in their zero-entry pool you can see a quick video rendering of it
HERE. You can also visit the resorts Community Hall which offers all kinds of fun for families, you can play ping-pong, foosball, video games, watch TV or participate in rainy day activities. There is equipment for basketball, bocce ball, tennis and shuffleboard. DVDs are available to rent (at no charge for Disney Vacation Club Members) at Community Hall. You can check the chalkboard in the children's area for games and crafts offered by the recreation team.
I think you've made a great choice, have a wonderful vacation!
