I'll soon be on my way to the Caribbean again, and this year I'll be laying over in the San Juan, Puerto Rico airpoirt for 4+ hours. I was thinking (like a true chipper) of taking a cab to one of the casinos if there's one fairly close to the airport. Here's a few of my questions:

1) What casino is the closest to the airport.
2) Which of the casinos within a fairly close taxi ride would have chips more desirable for trading.

Language isnt an issue since my wife is a quite fluent at spanish.

3)Are there any that might have two scasinos in close proximity?

4) any and all advice is welcome since even though I've traveled extensively to the caribbean, I've never visited Peurto Rico before.
