I would not stay here because I like going to the beach. This province of Costa Rica (Guanacaste), is well known for frequent crocodile attacks, as well as occasional shark attacks and deadly snake bites. While crocodile attacks are most common in rivers, they also sometimes take place on the beaches and even in the surf zone. If you like the tropical scenery there are much better places to go for that (Hawaii, French Polynesia, Fiji, Mauritius, Seychelles, etc.), while if you like the best beaches then the eastern Caribbean, Greece, or the Maldives is the best option. Costa Rica's luxury hotels are overpriced in general given the safety risk in my opinion. The best way to see Costa Rica is to go on a carefully selected guided tour. Save the hotel points for luxury hotels in better spots.
This touches on a broader point that should be made. Resorts (as well as environmentalists) all around the world have a systematic incentive to downplay safety risks from wildlife because they are largely uncontrollable and demand will be reduced if guests have full information. Resorts in Thailand and the Philippines, for example, are notorious for underreporting and warning potential guests about the prevalence of deadly box jellies (which are especially common in the central parts of the Gulf of Thailand like Koh Samui, as well as in Luzon, Cebu, and Palawan in the Philippines). Many tourists are unaware that there are crocodiles on the lagoon side of the resorts in Cancun (as well as in nearly all of the western Caribbean and central America). The stingray tour operators in the Caribbean systematically downplay the risk of stingray attacks (which happen quite often on the tours). In addition to price and brand I encourage always checking the wildlife risk of any resort you consider visiting.
