Phenomenal trip, longest cruise we've been on. Purchased one premium beverage package as wife does not drink as much as me. Cabin was great, in elevator hallway, but minimum noise. Joining cruise critic a few months prior made all the difference. We met so many great folks from all over the world. One of our new friends won an upgrade to a penthouse suite during day one bingo. She invited a bunch of us (cruise critic members) to her penthouse as we transited the Gutan Locks. That day alone made the entire trip.
Shore excursions...would not recommend snorkeling in the pacific, or at least not this early in the season. Best excursions -- hike to plyacana volcano in Guatemala , Segway tour in Columbia (private), and grand tour (horseback riding, zip lining, and, crocodile river ride) in Costa Rica.
Dining in Blu was great, but menu choices became redundant around day 12. Service was great, food was great. But keep in mind we are relatively new cruisers...many cruise critics said food was not up to par from previous cruises with Celebrity.
