More quick abbreviations:
DH - Husband (the "D" can stand for Dis, Darling, Danged, Dam, Dumb, etc
DW - Wife
DS - Son
DD - Daughter
SIL - Sister In Law or Son In Law - gotta look at the context again
yo - Years Old (as in 11yo which is the equivalent of DD(11) or DD11)
KTTW: Key To The World card. Same as staying at a WDW (Walt Disney World) resort - you room key. On the ship it's also how to pay for purchases while onboard or on CC (
Castaway Cay)
LOL: Laugh Out Loud
ROLF: Rolling On the Floor Laughing
Now about your cruise. 3 days is really short and goes by quickly. I understand the sea sickness possibilities (I take dramimine EVERY day while at DL (
Disneyland) or WDW. Knowing this, I start taking dramamine the day before leaving on a cruise (if not at a park - if at a park then the meds are a given). Well usually after a few days I forget to take the meds and have never had a problem on a ship (small boats for snorkeling excursions - yes::yess:: ).
Since this will be your first cruise try to do a 4 nighter. Day one you leave PC (in this case PC means Port Canaveral - context again
) at 5pm and dock the next morning at Nassau. You leave Nassau very late in the evening and the next morning you dock at Castaway Cay. You leave around 5pm and the next day is a day at sea. The captain is always just looking for good weather and seas to sail the ship in so you can have a glorious day in the sun. And you are in the relativly sheltered waters of the Bahamas.
