I have to agree. If you can get a suite level room for only $300 more than 2 Cat 11's then go for it. In our experiece it has been a lot more money for the Suites.
The concierge level cabins are the suites: Cats 1, 2, or 3. The aminities you receive are: pre-boarding, a meeting with the concierge team to make all of your reservations(Palo, spa, hairbraiding, and so on). Everyday the cocierge team will check on you and give you a weather report for the next day. Sometimes they bring coloring books and/or acarde cards for the kids. And every afternoon/evening you will receive a plate of goodies. You can order off of all dinning room menus for room service. And for your tips you just fill out the paper and give it to the concierge team and then they will take care of getting the slips for the CMs. Tips are not higher with the suites so you will not have to budget anymore for them then you would for two Cat 11s. Tips are based on the number of people cruising not on the level of room.
Many people will tell you they like the space for the extra room and not the concierge service. We like the suite for the extra space and the convenience with reservations. We also like having the concierge team available should we need something.
