Pros
Serenity was great - quiet and comfy. Entertainers on 5 casino bar all good - bit loud at times. Piano bar excellent- disco was a dud:(. Spa - free seminars for women had good presentation and info. Rooms were clean and larger than other ships. Service in rooms was great and also in dining room. Burgers were outstanding! My friend ate there every day! Excursion in Cozumel - regatta sailing race was the chance of a lifetime to experience! Also Roatan glass bottom boat tour / sea and see with Julio was exceptional!
Cons
Cabin was clean and larger than other ships but stains in carpeting. Stewards /Rickie was excellent! Room service was good/prompt.
