One reason for the hard, concrete beds is ease of recovery from hurricanes! In 1995, we had planned a trip to Coz (our first), arriving on a Sunday in October. The Thursday prior to that, Hurricane Roxanne really tore up the island. The jungles were fairly bare (looked wierd, no leaves on a lot of it), several hotels were closed for a while, the criuse ships didn't show up, it was fairly empty. BUT, I contacted Dave at Aldora divers (whom I was diving with) and he called me on the phone from Coz, and said the phones worked, power was on, and 1/2 or so of the hotels in business. so come on down! And we did. We moved to La Cieba hotel, and got there Sunday. about 1/2 their rooms were out of commission (they lost most of their windows and it all got wet). But they recovered quickly. Throw out the mattresses, wash the bed linens, sweep and hose down the room (concrete beds and drains in the tile floors). New glass, hang the curtains, new mattresses, and voila! back in business. So the concrete pedestals and tile floors are a survival mechanism!
BTW, the vacation was GREAT! The island was fairly empty, we got great service, diving was superb by about Tuesday when the water cleared again.
