Cool, The hotel is amazing, There is masses of space on the beach. The Food is really really good, so much to choose from. The evening entertainment isn't great. Go down to the pools before they close at about 18:00 as its getting dusky you'll likely have it to yourself.
You can get the Shuttle bus or water taxi to Coco beach. The sunset cruise from Coco is nice. The hotel also runs a trip to Tamerindo, which is worth a visit especially if you want to surf.
There are massive Iguanas everywhere, They will sit on the sun loungers next to you. Take a torch down to the beach at night and look at the Bats and Hermit crabs.
There is an animal park next door to the hotel which is small but nice there's plenty of Sloths there. They have a zipline thing as well but we didn't go on that.
The Hotel has a dive center, which is good if your a diver try and get out to the Catalina Islands. It also has a small Casino and Nightclub a few small shops and a Gym.
With the sea in front of you walk left along the beach, about 500m along in the mornings you'll find the spider Monkeys near the sign for the monkey bar. If you want your own tropical beach walk to the end of the beach where the rocks start you'll find a steep track heading up the hill (Fairly steep) it goes up and over the hill to the next beach If the tides in you'll most likely have it to yourself.
Also at that end of the beach is a track you can follow that and it goes in a big loop back to the front of the hotel, Probably about a mile, You can spot the howler Monkeys along there.
On the beach lots of dead puffer fish where getting washed up so mind you don't step on them, you may also get dead turtles wash up as well

The sea also had Tiny jelly fish wish gave a minor sting, like a stinging nettle don't know if it's like that all year.
I seem to remember taking about £500 with me to cover excursions and diving. The Hotel is a long way from anything, so nothing really for you to spend money on there. If you've already paid for excursions you may need less. The longer excursions will normally include food. There is an ATM at the hotel in the casino, but it ran out of money quickly and was often broken.
