We just finished a wonderful vacation with Tico Tom and the costaricanresource.com group. Tom Rainieri is an honorary tico and his guides are all certified and speak English and Spanish. They couldn't have been more knowledgeable and also willing to work with us in everything we wanted to see.
You finished an activity and there they were with towels, water and a snack.
The hotels we stayed at were great and the meals were wonderful. The pride was very evident in everything they did.
His tours also include a videographer to record everything for posterity.
I cannot rave enough about this group and this is my 5th trip to Costa Rica.
Check out the website and give him a call.. you will see for yourself.
