HELP!! Should we avoid Tortuguero in June
 

We have a three day trip booked to Tortuguero the end of June. I am reading a lot of posts on the internet as well as some travel books that we could encounter some heavy rain. I am wondering whether or not we should cancel our plans and go to Monteverde or even Panama. (the rest of our trip is a week cruise on Cruise West down the Pacific Coast). Please help.
