We plan on vacationing in Costa Rica at The Hotel Riu Palace from May 24 - May 30, 2013 and was wondering what the weather is like at the end of May? Does this area experience alot of rain at the end of May and also when it does rain are we talking hours of rain or brief showers. Also how is the beach in this area? Or would the Westin Hotel be a better option for weather, hotel and beach? What is the average day time temperature in this area?
