Room: We booked balcony rooms and had the divider opened between the 2. We had rooms 6398 and 6400. This was the perfect set up. Our son could sleep in the room with grandma, have his own bed instead of a couch and still move freely between the 2 rooms via the balcony. Unfortunately, these rooms were located right above the One Small Step Dance Club. This proved to be a disaster :) You could not hear the music, but the base from the music was sooo loud it vibrated the floor, walls and bed from our cabins. You could even see ripples moving through the water in our glasses. We could not turn the TV up loud enough to drown out the noise. We made multiple complaints to guest services at times begging them to please turn it down as it went full force until 3:30 am each morning. My initial frustration is the guest services attendants appeared amazed that there was a complaint. Carnival did address our concerns appropriately. The ship was initially full, but someone debarked on the first port and we were given their balcony room. We no longer had the adjoining balcony set up we were so happy about, but they did give us 3 keys to the other room so our son would have a key to both. The cabins were on the same floor and relatively close ... just the new one did not come with additional noise. All 4 of us were refunded some money on our accounts for the inconvenience and we all thought it was a fair amount. * I would hope in the future Carnival would treat these rooms like an "obstructed view" and add a disclaimer during booking. I am certain there is a population of their customers that would not be bothered by the noise... however, I feel comfortable saying most unsuspecting grandparents and families are.
