So 6 of us decided this year to take our yearly vacation to Costa Rica. Our ages range from 21 and 35 (all brothers and sisters) We're looking at May 25th to June 1st. I'm aware that its the rainy season and I'm a little bit nervous on making plans. We decided so far on going to riu guanacaste to get some beach time. I really wanted to add the arenal volcano to our trip and was debating on leaving guanacaste after on friday and driving up to arenal for 3 days. As it is the rainy season I'm not sure anymore if its a great idea. The other options would be to stay the whole week in guanacaste and do excursions from that point. Any feedback is greatly appreciated.
