DME is the same service at all resorts. How long will it take for your luggage to arrive? Probably about 2-4 hours after you land. The key here is to NOT plan to sit and wait for your luggage, as that would be a HUGE waste of time. DME luggage "magically appears" in your room whether anyone is home or not.
We packed what we immediately needed in our carry-ons. When our luggage arrived inside our room, we didn't know it because we were in the pool enjoying the start of our vacation. Especially when traveling to a warm weather area, packing for the first 24 hours takes up very little space. Try it! Complete change of clothes, swimming stuff, PJs, toiletries -- it takes up surprisingly little space.
Actually, I ALWAYS travel that way whenever I fly, just in case the AIRLINE delays our luggage.
