I may have the same situation. My DSis might come with us now. I have all my ADRs for 3. I also figured adding one more shouldn't be a problem. We also figured it would be better if we had an additional room too as the 3 of us (My mom, my sis, and myself along with my DD6, would be a little too crowded for 10 nights.) And you now how sisters are

. We always have a disagreement about who drives.
Knowing my sister though, she may wait too long to decide! I've told her she needs to decide very soon (
Free dining offer ends 6/25) and already the flight we are on has changed from $218 rt. to $292. She could take a later flight there (and use Magical Express) and return home with us for the same $218. Actually, this wouldn't be that big of a deal for her. When we went in Jan. she decided last minute to join 5 of us. (we already had 2 rooms). She flew with us to Florida but took a different flight, and airline, home. She left about 1/2 hr. before we did and arrived about 15 min. after us. She said it was fine, she talked to other people on the plane.
So,
if she goes, should I change my dining plans too?
