We're staying at Caesar's for the first time in December. We have a comped Roman Tower room (oldest room, right?); it's through one of the Choose Your Escape trips. What would be a reasonable upgrade to request at check-in (with or without the $20 thing)? Our stay is for two nights the week before Christmas, midweek. From what I understand, it's at the tail end of the NFR and fairly quiet out there at that time. I don't want to aim too high, but.... Thanks.
