My family of 5 is arriving at SJO for our first trip to CR at 4pm on April 10th. We had planned on spending that night plus one more at Hotel Buena Vista before an early departure on 4/12 to Dominical. Will things be closed or it be too busy in Alajuela on the holiday for us to drive ourselves to Poas crater on the 11th and then perhaps Doka and/or Sarchi? Will there be holiday festivities that our family would enjoy on our own? Finally will there be excessive traffic in the morning on 4/12 leaving Alejuela and heading towards Dominical? We are wondering if we should rent a car right after we arrive at SJO or hire a driver/guide for our time in Alejuela and to bring us to Dominical. Thanks!
