It is a bit difficult as you have said!
"NCL regulars" would likely answer questions you might have about specific excursions on the PORT listings. I read the port posts anyway to get a feel for what sound the same as NCL's descriptions.
Or, you might look for Ship/Itinerary specific NCL posts in this forum and perhaps you'll find info you want. Trying using the "Search" feature (in the upper right hand corner of this page).
Possibly things will be posted closer to your sail date. I have a list from our cruise December 2022, which I hope helps ... (prices may have increased):
Fins & Snorkel Vest: $24 Adult / $19 Child
Snorkel Vest Rental: $9
Snorkel Equipment: $37 Adult / $22 child
Full Face Snorkel Mask (upgrade) $45 Adult / $29 Child
Soft foam mat (floats): $22 each
Stand-Up Paddle Board: $39 each
Just to verify the above... within NCL Promotional Terms and Conditions it states:
For port calls in Great Stirrup Cay and Harvest Caye, the promotion and $50 Shore Excursion Credit does not apply to equipment rentals.
Those enclosed areas are crew only access stairs.
Possibly info on this link may be helpful to you:
