Our friends were in similar situation for February. Katy (mgr of LaPlaya) managed to arrange rooms at Esmeralda. Perhaps she can do the same for you...
Katy is a sweetheart and made arrangements for us to stay at Esmeralda as well. We stayed at Esmeralda for 6 years in a row and the quality of the rooms deteriorated while the price went up every year. The people at Esmeralda are very nice and CoCo's was always a favorite for breakfast and lunch but we are a bit gun shy about trying them again.
