WOW Maria67, your excitement is palpable
You'll love CN.
Shells - We've never really found too many shells on the beach, some small ones perhaps.
Camera - We use an inexpensive underwater point and shoot and an inexpensive underwater video camera.
Shopping - the resort has a couple of gift shops and will bring some vendors on property most days you can buy the typical stuff from them, there will also be some vendors walking the beach with bracelets, dresses etc...You can also turn right on the beach walk past the Riu Palace, then Sunset at the palms and just past the Office of Nature there are vendors set up there.
I will also, recommend the "one love bus pub crawl" much fun!! You can read the reviews below:
