I'm not sure with today's limited number of places on Orient Beach, but in the past some places did ask the ladies to put on a coverup when dining or having a drink in their establishment. I know one woman who was asked to do this and she was furious they asked her to do this and vowed never to go there again (I won't name the place). Of course that wasn't the case at Papagayo or the Perch Lite, so it may be worth asking places like Kontiki and Bikini Beach and KKO what their policies are today regarding this.
