Good call.
Hop on mydisneyexperience.com and do some restaurant searching, you can choose specifically the resors you are interested in. That luau dinner your friend mentioned is at the Polynesian. As for other recommendations - we very much enjoyed dinner at The Wave at the Contemporary in November. 4 adults, all with different entrees, and none of us was remotely disappointed.
As for getting reservations:
A. you may be surprised
B. the times available might not be exactly what you want, but snag them anyway if you think they'll work
BUT...C. keep checking back, especially in the week or so before your dates. People snag up all of the reservations they think they might possibly want at 180 days out, then drop a bunch as their plans firm up. You can cancel most restaurants on site 24 hours in advance without being charged, so plenty of people take advantage of that.
THANKS. Will do. So, what you are saying is that there is a *direct* boat ride from FW to Poly and Contemporary?
