We used to do that until a CM told us that we had to take the table they were offering us or forfeit the ADR. We begrudgingly took the table, ate a hasty meal (spending much less than we would have originally), and rushed off to find a viewing spot. We have not been back to R&C since.
Hmmm, if they do that this year, I'll forfeit the ADR, save a good spot, and send the rest of the group to get treats from the kiosks!
