It looks like the prices differ between the generic excursion listing on NCL’s page and the excursion listing for your specific cruise.
I just checked ours. The clamshell rental on NCL’s generic excursion page is $48.40 CAD but when going through my booked cruise, the clamshell rental is $62 CAD. sorry I can’t see it in USD but it shows how they are different prices. If the loyalty status came into play, going through the booked cruise where I’m logged in to my account would be lower but it’s not, so loyalty discount doesn’t come into play here. Not sure why it’s higher for the booked cruises other than maybe it’s based on length of cruise. Mine’s a 10 day. Although that doesn’t make sense either.
Question: if I use my $50 excursion credit to book the clamshell then later want to cancel and book a different excursion, does the credit get returned so I can apply it to the new excursion? didn’t want to book the clamshell now if it can’t be cancelled/refunded.
