I would like to report that both Casa Caroline and Sandwood Villas located in the Xcalak vacinity were very helpful working with me to set up accomodations for a party of four divers.
Casa Caroline did not have room during our time frame, but assisted in telling me about other facilities. Sandwood Villas is located about 15 minutes north of Xcalak and offers two bedroom units. Andy and Ruth were most helpful working with me and refunded all but their expenses from my PayPal reservation. I cancelled because Chinchorro trips were not available due to boat repairs. Since I did not stay with either I cannot report on their facilities. I would use either in the future since they were so helpful.
