We are looking for a trip with three grown sons, youngest is 16. We have never been to Costa Rica and most packages from Toronto are AI which is actually best option with our family for convenience and price. I am also looking at various week long tour options. We are interested in touring the Arenal Volcano, Monteverde and would love a river tour also. What is the best area to use as our base to keep travel as short as possible for the trips? I am considering Playa Tambor, Flamingo Beach, Playa Longesta, Occidental Grand Papagayo and Hilton Papagayo based on dates of departure from here as we have a limited time that we can all go over New Years. We would love wild life at the resort and while snorkeling would be great, not a must. Also, are overnight tours offered once there that may combine some of these trips? We have no interest in renting a car. Any comments or advice would be appreciated. Thank you.
