We went onboard the Mariner of the Seas last Dec 24, 2015 for a 5 night cruise. Port of calls were Port Klang, Langkawi, and Phuket. Stops were so-so but the ship was one of the best we've tried around Asia. Establishments/ areas of interest on deck 11 are as follows:
Bridge overlook, Vitality at sea spa, Fitness center, Solarium, Solarium bar, Pool bar, Sea trek dive shop, swimming pools, whirlpools, Chops grille, Windjammer cafe, Giovanni's table.
