I've just finished reading some scathing reviews of hotels in Costa Rica. Here is a thought- if you don't like mosquitoes or insects, maybe A tropical vacation is not for you. It blows my mind that people will give a place a bad review because they are in the jungle and there are bugs. You want to see monkeys? Well, the mozzies come with them. It's a package deal. Also, if you are only paying $50 for a room, perhaps you should lower your expectations.
End of rant!
I'm in CR for the second time in five years. It is fabulous. The people are lovely. Open your heart and open your mind. Pura Vida!
