we sailed on CB over Thanksgiving at 100+% capacity - way understaffed, and could only get into Sabatini's on the first night (we did, and was excellent), and not into Crooners at all. mdr took 2 plus hours even at our table of two - but was almost treated as a table of 10 or so - as the waiter(s) served multiple 2 tops at the same time from the galley.
that stated - we're back on the CB - maybe - for a cruise at the end of October if we don't use CFAR.
