Those are the three that we use but Meson only as a last resort...just don't like shopping there for some reason. The three sell the same stuff so there is not much variety but for some reason there is a big difference in prices on the same products. Some days you can save by shopping in Tropical over Jose Luis and other days it's the other way around but I can't tell you why that is.
As for movies, 6 months late and probably already out on HBO you'll get the blockbusters in Playa Dorada but any popular movie will attract a big crowd and that means that you'll have a circus in the theater with cell phones ringing, kids crying, people chatting etc.
Library??? Oh, I remember...they have books there, the kind with more words then pictures! Forgetaboudit!
