The Mariner of the Seas was fresh off of a $120 million refurbishment. The ship looked crisp and clean. Our embarkation was smooth getting to use the Suite line because of being in a comped junior suite.(thank you URComped!) Our stateroom was perfect and there was 2 letters from the casino hosts. One for me and one for my wife. The letters welcomed us to our Prime tier in casino royale. Not bad for our first cruise on Royal Caribbean. This tier gives free drinks in the casino, no fee cash withdrawals and also a yearly free cruise in inside stateroom. Very nice. The casino was not. Rowded at all and feel it had a good mix of slotas...wonder wheels, wonder tower, buffalo gold, dancing drums, ect. We received daily gifts from the casino hosts which were greatly appreciated. In addition on the last night we received a certificate for a free cruise. All in all...great ship..great casino and a great time!!
