Hi, I haven't cruised with Princess before, but I'm looking at a few cruises. I'm a bit confused about the pricing and hoping you can help because I can't find the answer. I see everywhere that it's 60/80 a day, but every cruise adds more than that to the standard price on all the ones I've looked at. I don't know if it's something to do with me cruising solo? Or does Princess charge an 18% gratuity on the package? Or something else I'm missing. The last cruise I priced out is adding $74/day for the Plus package not $60. Though that's more than 18% so I'm just confused! (I priced the same one for 2 and it's $67/day.) I saw that you can now buy it on board, so if they don't charge gratuity on top of the price it looks like it would behoove me to just buy the package on board. Do you still get the Medallion accessory with Premier if you buy on board? Thanks!
