We anchored outside the marina in front of the Las Hadas hotel.  Holding was good and the water was about 18′ deep. The marina office can process your paperwork and they didn’t charge us for that service, which saved a big trip to the Port Captain.  We paid 300 pesos for a week’s pass at the hotel/pool.  Nancy could not get enough of lounging by their totally awesome pool.  You can also use their showers for the fee, but I don’t recommend it…I don’t see how a boat could use the marina itself…it was 99% full and it’s circular, so Med Moorings is the standard.  Not something I’d want to try too badly in those really tight quarters.  We also looked at the other recommended anchorage while we were downtown and would’t really recommend it.  It was packed with crappy fishing boats and didn’t look like a place we’d want to be.
