Meeting Friends in Costa Rica?

So one day Trevor was talking to his friend Aaron, and he mentioned that they were planning a trip to Costa Rica for March break.  Cool!  Aaron and his wife Allison invited Trevor and I for dinner and we had fun comparing notes and itineraries.  They are travelling with their child, Rowan, who is in Grade 9.  Coincidentally, they are flying to Costa Rica the same day as us and flying home the same day as us (different flights though).  We are doing several different cities in our itineraries but are in the same place for our first destination as well as two thirds of the way through, we overlap for one evening in Monteverde.  So we've booked a waterfall hike together in Curubande, and we've made a reservation to meet up for dinner in Monteverde.  Can't wait to hear all about our different adventures!  Allison and I have also been texting back and forth with planning advice and comparing notes.  So fun!
