If I hadn't stayed at the Nayara for a night before coming to Tabacon, I would be telling you this was by far the best place to stay in Arenal. Even with that comparison Tabacon holds its' own. It's a beautiful and relaxing hotel. Luxurious and with great views of the volcano/rainforest and a very good buffet at the restaurant. However, I was even more impressed with the Nayara. Why? Well, the buffet was even better in my opinion and their restaurant was superior. More importantly, Each room had private terraces with personal hot tubs and hammocks. The Nayara was really the best place for someone on a honeymoon. The grounds were superb and the hidden Jacuzzis and swim up bar were nice touches. They even had indoor and outdoor showers with each room. But on the other hand, Tabacon did have the thermal pools - the best I've ever seen and I'm thinking they may be the best in the world. Entrance was included with our stay. The thermal pools alone make Tabacon an excellent hotel - but still #2 in Arenal in my opinion. I would have stayed longer at the Nayara but it was booked beyond the first night. Also, I was travelling with my brother and it felt a little weird staying at a "honeymoon" type hotel.
