Have you checked any of the Orient Beach hotels
ie Alamanda, La Playa [was L'Hoste] Palm Court, Esmeralda, PLantation, Blue Beach etc?

Generally a room with some kitchen facilities [depends on the hote] some sort of breakfast and maybe chairs for free at a beach bar

Just checked Alamanda's site as an example for your dates, they have rooms

What about contacting Jim Ruis? for rental info

Just thoughts
