We have stayed at Atlantis before in the Royal Towers and that was comparable to a middle of the road hotel in the states. The Cove was a very differnent experience with access to the Cain pool and their private beach that isnt available to the guests on the other side of the resort. The experience was very different from the attentiveness of the staff down to the in-room perks. All of the rooms are suites and the bathrooms are large and spacious. The upgrade is well worth the additional cost and I think that you will be very pleased from a cost-benefit scenario.
