I would suggest that everyone keeps calling! I was able to move a few things around yesterday morning that I was not able to move before. Package balances for this time of year are due so there may be people canceling.
Also, don't forget with their wacky reservation system that they may say that they do not have a table for a party of 5 but do have one for a party of 6. Last time I checked, parties of 5 or 6 typically are seated at the same size table so how could one be "Available" and not the other.
Good luck!
BTW. . .I already posted this yesterday but just in case you missed it I cancelled two ADR's yesterday.
Tuesday, 11/18 - 4:15pm LTT for 5 but at two tables so 2 and 3 would be open too.
Wednesday, 11/19 - 4:50pm 1900 Park Fare for 5 but again for two tables so a smaller party could snag these too.
