My husband and I with our 4 and 6 year old boys stayed at Arenal Oasis the first week of March 2012. The cabins were cozy and clean. The grounds are well kept and tidy. There is a lovely nature trail that is self guided and has a butterfly garden and several stops along the way where you can see snakes, lizards, frogs and spiders in glass tanks. We would have liked to do the night walk but I felt that $80 usd was out of our price range to take our family of 4. It would have been nice to have a family discount offered. Breakfast was include and was ok, not very hot, but the varity of birds surrounding us as we ate made it very pleasant. If you go during the first weekend of March be prepared for the very loud festival in town. We chose this place for a peacful and quiet location and were not disappointed until about 10pm when the music started in town (which was about 3 km away). The music was so loud it felt like it was in the next room! Not anything the owners can do about it, but just be aware that if you don't want to take part in the festivities you will be exposed to a long night if noise regardless.
