I’ve amended the post, and the number (now post 647), about the 10% discount on Shore Excursions. As Scots Caz says, this is generally when you book 3 or more excursions on board for another booked cruise.
Yes, some post (#) numbers may now be inaccurate if posts have been deleted. I will try and trawl through them to check. It’ll be slow progress as I’ll have to do it a page at a time. I’ve checked the first page of posts (#1-#25) and they are all accurate.
