This was our second cruise on Liberty. I wasn't sold on mega-ships after our first, but this cruise seals it for me. Bigger is better if you're seeking bells and whistles, and have the patience contending with more people - and keep in mind that size has its price in convenience of moving about the ship efficiently.
From Baltimore the four of us flew into Miami International, where I partook of my first Cafe Cubano while headed toward the luggage claim - at just 75 cents it is the biggest bargain in town. What else can one buy at that price in an airport? Standing near our carousel was an RCCL representative who told us to take a taxi to our downtown hotel - faster, cheaper and more efficient. Best tip of our trip. A shuttle bus would have cost us about $70 altogether, while the metered taxi was $35. So, thanks for the tip.
We stayed at the recently renovated Marriott Courtyard Downtown, great location near Bayside and the port, and reasonably priced at just over $100. We had a room with a view to the port, between intervening buildings. Many nearby stores for last minute needs.
Unique room with added Ben and Jerry's" perks. "Plus" is the room gets some "outside light" from its mall window. We experienced no noise from the service area adjoining the room, nor from the ice cream shop below. But if you're early to bed you'll be in for night-after-night parades, dances, and other assorted spectacles that continue past midnight. That's true of all the inside Promenade rooms.
