Liberty of the Seas - Western Caribbean
My sister and I (late-20s/early 30s) booked this cruise as a celebration of her new job and we booked very last minute (about two and a half weeks before the departure date). There really is no advantage to booking cruises last minute...the prices of cruises actually go up as it gets closer to the departure date. Still, the pricing was reasonable (about the same as if I had booked about 6-8 months in advance). We left our guys (husband and fiance) at home since they couldn't get the time off!
This is my second RCI cruise - the first was on the Mariner of the Seas in February 2007. I have also done a cruise on the Carnival Liberty in November 2007. It was my sister's first cruise.
