We had the 2+1 lockout, and it provided our family with teens the room to spread out and have privacy. It had a great layout overall. The kitchen was very convenient, although we did not use it much - for anyone who wants or needs to cook their meals, you will have everything you need to do so. Having a washer/dryer came in handy for an 8-day stay, and the heated pool and hot tub were nice as we had a few days of chilly weather. The other pools at Atlantis are not heated. The shuttle was about 7 minutes to any of the other Atlantis properties, and we never waited more than 5 minutes. It is also a very nice walk through Marina Village to get to the Royal Tower, where the main water slides are. Overall, we preferred the tranquil environment of Harborside as a nice break from the busier Atlantis. If I were only going with adults or my spouse, I would maybe have selected The Cove, but with kids, I don't think you can beat the space and privacy of Harborside.
