We have attempted to book what looks like a really great tour in Puntarenas, Costa Rica, but no one else has booked yet, so no tour so far.
Anyone who is going to be there on April 30/09 (we are on Island Princess) should check out this web site and make a booking. It seems much better than what Princess offers, and at a much better price. Check out this web site.

Hope to see you there.
