Haven't been on a short cruise in some time but my dh and I will soon cruise on NCL's Sky. We are planning to bring our own masks, snorkels and Mae West vests, but would like to avoid bringing our heavy fins (baggage wt. limits and fees being what they are). Does NCL let people rent JUST fins or do they only rent out a complete snorkeling equip. pkg? What about while we are in the Bahamas. For instance, can we rent fins on board and take them w/us to a beach? Also, any info. re: the prices to rent fins (or the pkg.) would be appreciated!
