Hi, Gail!
The Disney All-Star Resorts (Music, Sports and Movies) have rooms which connect to each other via a shared interior door. When you make your reservation, simply request connecting rooms. We've stayed at both All-Star Music and All-Sports, and have had a door which connects to the room next door each time. Connecting rooms is a great option when your family needs a little extra room, or a second bathroom. You'll find that the All-Star Resorts are wonderful, too!
Regarding free dining, Walt Disney World often offers such incentives during non-peak seasons. For example, there is currently a
Special Offer for Guests for up to 30% savings at select Disney Resort Hotels for "stays most nights February 18 through March 23, 2013 and April 2 through June 14, 2013." Check back on the Special Offers page from time to time for information about Free Dining in the future. If you don't need to worry about a school schedule, then you'll surely be able to take advantage of free dining once it's offered.
Have fun planning, Gail! Send more questions as you think of them, too. We love to help!
