There is absolutely nothing wrong with that. I called recently and tried to get a table for 5 at CRT and nothing was available. I then asked, "Is a table for 6 available?" She replies, "Yes, there is" I said ok a party of 6 then. She had absolutely no problem with it and didn't even question me. She totally understood and actually laughed about it. A party of 5? A party of 6? Isn't it the same size table?!

I told my hubby what I did (he is oblivious to ADR's and anything Disney) and he said that was nutts that they would turn down a family of 5 but ok a family of 6 when it is the same size table. Crazyness. The system is totally flawed and some people are getting turned down for restaurants that they want because they don't have an extra person.
I am extremely excited about eating at CRT for the first time. Flame me, get me, tell me off. I don't care, you still won't wipe the smile off my face!

pssst I also got Le Cellier, but that is for a party of 5 so you can't yell at me for that
