if you do it in the morning before it gets too hot!!

It's been really warm here this year (something to do with "El Nino effect") so it's very easy to get to. Just turn left out of the front entrance and left again where the road follows the wall of the hotel and keep going until you get to Costa Caribe. Main Entrance will be on your left. Or you could wait until evening (but the person you're looking for may not be working then) and take the "Casino bus" from La Cappella to Costa Caribe.
