One Bedroom Premium at Atlantis - inconsistant occupany numbers

Hello, I am renting a week at Atlantis from a Starwood Vacation Ownership member. We are a party of 5. According to the Atlantis website, the One Bedroom Premium units should accommodate 5 so that is what we rented. However, the SVO website and the confirmation e-mail I got say that the unit accommodates 4. I have called both SVO and Atlantis and they both assure me that there will be no problems with having 5 in our room and with getting 5 wristbands for the waterpark. However, no one is willing to put this in writing (aside from the SVO member with whom I signed a contract.) Does anyone have definite knowledge of people checking into a 1-bedroom premium with 5 in the party and not having any problem?

There is no problem with 5 people checking into the premium 1 br at Harborside. There is only bedding for 4 and there is an additional charge for the cot.

Thank you, Tracey!
