We are 3 travelers and are flying into LIberia on June 13th to June 20th. We basically have only from Saturday to Thurs in Costa Rica. We are targeting three days to spend in the Rincon De La Vieja area to do the adventure tour in Hacienda Guancilein, visiting the main park, and seeing the Cortes waterfall. On Monday or Tues, we are targeting to go to white water raft in Tenorio. After that, this leaves Tues to Thurs as unknown. Should we go to MonteVerde or Arenal in that area? We will not be renting a car, so will have to hire private transport. Is it worth the expense of private transport to go outside the area to Monteverde, La Fortuna, Arenal or better to stay in Rincon given only 6 days?
