MLD is newer and probably a .5 star above the MCSM. We have only stayed at the latter but walked through the MLD when it was new. It is larger (boo!) and would have more amenities. I don't think it's adults-only, but I know for certain that MCSM
is adults-only. They share the spa, which is lovely. Both are on the same gorgeous white-sand beach. I'm sure others who have been to both can give you a better comparison than I. (Is this the anniversary trip being planned?!

) TC
