It's family-friendly (one pool is adults only and the other for all ages), so a good option if you have kids in tow, as there are a handful of outdoor activities they can get into right on the property. The seaside rooms have balconies seemingly made for enjoying coffee with a view in the AM (the buffet breakfast downstairs is solid, too, though). Probably most notable about the suites are their oversized glass-and-marble bathrooms, with luxurious waterfall shower heads and soaking tubs. The spa is fantastic, and three-star Michelin Chef Heinz Beck has a restaurant here, too. Also on Palm Jumeirah: There's a path for walking/running/biking, which you can pick up…
