Great location -- very handy to the pool, the Horizon Court, and the grill, and forward of the lifts and the stairs so there's not much traffic (except during bridge tours, if the security situation allows them). The only drawback is that it's a long way up when you return to the ship from a shore excursion and at the end of the evening. (No cheating and using the lifts, AKA "massive weight gain apparatus" -- guaranteed that you'll gain at least a pound a day if you use them!)
I do get to "cheat" legitimately.....use "mobile assistive device" for longish distances......BUT, I also have to eat very sparingly, as our house is on a low carb plan. We managed to stay on it on the Star, so plan to do the same on the Sun! Thanks for the info.........looking forward to using pool and spas at off hours.
