I'm actually trying to decide the same thing though not for a honeymoon. I have stayed at por but not the other two. I can say I do think por is very adult friendly and very pretty lots of walking strolls and privacy also carriage rides and the pool is dead quiet at night. So it would be nice for a couple. I'm planning a trip for 2 adults and to 16 year old girls and trying to decide if I should go por coronado or beach club any advice would be great.
