no, that's like a MAP, as you say. lodges inland do the same cuz food & drink not as easily accessible. i googled and saw coco plum island, kanatik, & hamanasi do - but not so near AC.
i would think all-inclusives on AC (excluding far north AC), while possibly bringing more package tourists there, wont necessarily bring more income to SP or Bz in general. why leave the grounds to eat, drink, shop or tour in town if you already paid for everything on-site?
when people ask me that question, i explain i think they'd be missing out on the fun of finding the many good places in there to eat & imbibe. some places need them, if food & fun is sparse int he surrounding area, but that does not apply to SP. JMO, as always.
