First time Oceania (possibly) cruiser - the TA I plan to use pays gratuities and gives SBC. I heard that booking excursions in advance to use SM excursion credit is important - and that a certain number booked can give you a discount. We're looking at 18 nights to SA and Antarctica. If I book excursions in advance and go over the SM limit, can TA SBC be used? I know on HAL, TA SBC doesn't show up until you are actually on board. Therefore, people pay for excursions with a credit card and then have the Shore Excursions desk switch it to SBC when they arrive on board, in order to use it up.
Is that how it works on Oceania?
