We just got off the Caravan tour on 15th Jan '08 and the Doubletree in Puntarenas nearly made me hate the trip.
It is very dirty in all areas: hotel rooms have floor tiles which are filthy with hairs of all kinds, tissue bits, crumbs, sand, etc.
The grounds has gum, cigarette butts and plates upon plates of the all-inclusive indulgence lying around for hours before they are bussed away.
The restaurants and public areas are filthy with fingerprints, stickiness, and an overall feeling of a rushed clean-up.
Public hotel bathrooms were disgusting. I would NOT reccommend this hotel to anyone.
I did speak to the manager. Hopefully he will make some well-needed changes.
In the meantime, stay away.
