We were at the Dolphin for 4 days & then the 7 day cruise. We purchased a 48-pack at the Target at the Florida Mall, and also a pack of swim diapers. I had a duffel bag packed in a suitcase; and I put the remainder of the diapers in the duffel bag, along with several bottles of water left over from a case we purchased. It was really heavy, with a half a case of bottled water + the diapers, but we checked with with our bags & it was delivered to our cabin with our luggage. The diapers on the shelf in Treasure Ketch were really expensive; if I recall it was about $8 for 10 diapers.
