There are slight differences. Phoenix is at the start of the High Rise section of resorts with the Villas built as beach front. The rest of the Divi Resorts are in the Low Rise (no higher than 3 floors) section of resorts. Dutch Village is not beach front. Rooms are across the street. Divi Village Golf & Beach Resort is also across the street from the beach but set on the golf course. Then there is the Divi Tamarin & Divi All-Inclusive. These 2 resorts are beach front. All the Divi Resorts offer an All Inclusive plan but only Divi All-Inclusive makes it mandatory.
With the change over to the Divi Vacation Club and Interval International there's been a lot of renovations going on. They started with Divi All-Inclusive and moved on to Tamarin (in progress). Dutch Village is next and finally Divi Village Golf & Beach. Room sizes also vary. All-Inclusive are the smallest, Tamarin is slightly larger. Dutch Village is more apartment complex style with each unit having a balcony. Divi Village Golf & Beach are the largest room sizes, have a balcony and the only ones in the Low Rise that have in-room Washer & Dryer.
One last note. There are shuttles that run between all 4 Low Rise complexes. You can eat at any of the restaurants at any complex, use any of the pools, enjoy any of the bars to find your favorite, and use the beach. Plus there's a single casino, The Alhambra Casino, that serve all the complexes.
