OK, that does NOT describe timeshares in SXM, at least. There are NO timeshares in SXM that have room service or concierges. They have activities' desks, but concierges, no. There are very few rooms in timeshares in SXM, other than the very upper tier units, that have in unit laundry facilities. Most SXM timeshares do NOT have BBQ grills. While I'm not personally familiar with LaCabana, I kind of doubt that they would have those amenities, but not familiar with LaCabana.
This is the southern Caribbean forum, not just SXM so I was talking about timeshares in a number of places and the ones I own or trade into have all the amenities I mentioned. Simpson Bay in SXM has grills. I've grilled out at Royal Sea Aquarium in AUA, Marriotts on Kauai, Oahu, shell resort on the Big Island. Had a terrible stay this year at Costs Sur in PV, but they even had a concierge. Must have had a good time at LaCabana -- don't remember much! When we fly MIA to AUA or CUR, we pack in checked luggage a few frozen porterhouse steaks & 4 lbs of shrimp to throw on the barbie to share with other guests. Love the potlucks. Enjoy your next trips.
