The hotel campus is huge, way larger than I thought it would be. The views were great. The hotel room was a bit small, as was the TV inside the room (maybe 19''). We did really enjoy the little porch and those comfortable chairs. The food was ok, nothing special. The price of the food and drinks in the gift shop were very expensive ($3.00 for a soft drink, and $2.00 for a bottle of water). I would advice anyone to stop before you get to the hotel, and buy your own drinks (beer, soft drinks, water, etc) and skip buying stuff on the resort.

The hot springs were a nice touch (don't be turned off by the water color). There were many different springs, with many different temps., it was neat.

The hotel seems nice, we didn't have that much interaction with them (which I guess is good).

Overall, I enjoyed the resort, but found the room a bit small and the food/drinks to be expensive.

Great location and perfect view of volcano from rocking chair on front of chalet
Had wonderful tour to see volcano close up withv Joeji in the pouring rain!

Restaurant good especially the buffet breakfast.
Ziplining on site - fantastic experience. The 3 boys were well looked after by two guides who pointed out wildlife
Girls enjoyed relaxing in the hot pools.

We spent 6 days at this resort. The grounds are beautiful. All rooms have a view of the volcano. Although our view was not super, we did not spend much time in our room during the day, so it really wasn't an issue. The views of the volcano from the pool and restaurant are amazing! Our standard room was comfortable and clean. The complimentary breakfast buffet each day was really good. Nice options for anyone. The pools and pool bar were nice. Bartenders friendly. The staff at the front were helpful and friendly too. The zip lining was awesome! Guides really helpful for first-timers and had a photographer to capture everything. Resort was only a short drive into town for shopping and dining. Only suggestion would be to have WiFi in the rooms, as the only other option was the Reception area and the Restaurant (which was not working during our stay). Would definitely stay there again and recommend this to anyone.

I'm at this time, with my family, my wife and my 2 childrens, in the Arenal Paraiso, hôtel Resort and Spa: rooms 272 and 273. The advice i can give is not to come here.
Ok the resort is in front of the Arenal volcano, but except this, there is not interest or pleasure to find here. The  rooms are simply uggly and absolutely not confortable. Obviously you should find a better place to stay.
