My friend and i are going on a 7night cruise to mexico on the Vision of the seas. And what to know how big is the inside cabins? And how good is the service onboard?
After 2 cruises on the Vision OTS, I can attest that the service is the best onboard. I haven't stayed in an interior cabin, only balcony and jr. suite, so I can't really answer that part of your question. The staterooms I stayed in were well layed out and nice, so I would assume the inside cabins are similar.
Majesty of the Seas - 10/03 & 02/07 & 11/08
Enchantment of the Seas - 10/04 & 10/11
Mariner of the Seas - 10/05
Vision of the Seas - 10/06 & 09/07
Carnival Liberty - 10/07
Adventure of the Seas - 9/08
Ruby Princess - 12/09
Voyager of the Seas - 9/10
Carnival Spirit - 11/10
Oasis of the Seas - 9/13
My first cruise was on Vision. The inside cabin, where we almost always stay, is not as large as on Princess, but certainly adequate. My SO claims to be prone to seasickness. Since the least motion is found in the cheapest cabins, it's a double winner. The food and service are great.
