costa rica volcano hotels

Going to costa rica for 8 days in march.?
What 2 (max 3) best places should i plan to visit in this short time, to get the best flavor of Costa Rica. Beach is a must, and so it the Volcano region. Recomendations for nice, cute hotels are also appreciated.
Thank you!
Beach: I strongly recommend you Playa Conchal… there are not sand, the beach is made up of little shells that’s the reason of the name. The nearest big resort is Meliá Playa Conchal.
Volcano: the Arenal Volcano, in La Fortuna city you would have a great view, specially at night that if you are lucky you can see the lava going out from the crater. And Tabacón Hotsprings are really near of it. The nearest big resort is Tabacon Resort.
Green Mountains: At Monteverde Natural Refuge, there are a lot of nature… from little frogs and orchids to huge tropical rain forest trees. The nearest resort, I don’t know but you can ask at www.visitcostarica.com (CR’n official site of tourism)
Why not???… you can also make a little stop at San Jose, I prefer spending more time at the ones I mentioned, but in Downtown you can know more of Costa Rica at different museums as: National Museum, Gold Museum and Jade Museum.
WELCOME TO COSTA RICA and ENJOY YOUR TRIP!
because, Costa Rica is Pura Vida!!!
