Review for Riu Guanacaste Hotel and Casino Review For Riu Guanacaste Hotel and Casino Google User Jun 16 '17 at 8:03 Nice place. First time at an all-inclusive resort. Beach was very rocky and had a lot of solicitors. We took our kids and they had a blast in the pool during the day. Restaurants we're not what they made them out to be, they didn't in force the dress code and they were more like a buffet setting than an nice sit down restaurant View full site to comment or like
