My wife and I stayed there last summer, planning to go back again this summer.
Definitely a very chill, laid-back vibe. Not a party place if you are looking for that. Pretty dead in the evenings after dinner. We were looking for a quiet getaway from the kids, so perfect for us.
Four restaurants, all were fine for an all-inclusive. But I am not a picky eater, so maybe not the best judge. Never had to wait to get a table, and often there were only a few other couples dining at the same time.
Really good staff who work hard to take care of you. Good spa and really nice gym.
Haven't stayed at Excellence, so can't compare. But have stayed at a few other all-inclusives including Secrets and Le Blanc. For the price point I think Beloved is tough to beat.
