Is there a standard cost to upgrade (once at hotel) or does it vary. Is payment in Pesos or what? What has others experiences been when doing this?
I don't know about Jacuzzi rooms - but I know that adding another person to your room is ridiculous to pay for at the resort, but when I added it through the people I bought the room from (Cheap Caribbean in my case) - it was cheap. Something like $140 a night down to $45 a night.
43 to 100 @ night depending what your upgrading from, credit card works, they give you a decent exchange rate for the most part
