When we decided to cruise this year I booked the RCL Liberty of the Seas then got cold feet when it turned out that it was going to be almost $3000 more than Carnival. We booked the Valor but then switched to the Glory because we liked the itinerary better. We have previously been on both the Valor and the Glory.
My husband and I cruised with our 3 kids (daughters 20, 18 and son 14) and two of my daughter's girlfriends aged 18 & 19. We booked 3 cabins on deck 6. A balcony for us and 2 inside cabins across the hall. Our cabins were 6294, 6296 and 6298. The location was pretty good. We liked being midship, even though in the past we have been closer to the back.
Pre Cruise - stayed at the La Quinta FLL which was a TOTAL DIVE. Avoid it if you can. Way over priced for what you get and really not close to anything. Airport shuttle was the only good thing about that reservation.
Balcony 6296 - good location to front of ship... kind of a hike to the back and up the stairs to the food. LOVE having a balcony -- wouldn't cruise without one.
Kids had inside cabins 6294 and 6298 and they could clearly hear the singers/music from the atrium lobby.
