hi Paradise.
2 things.
1st: if you work as a rep and your hotel where you are does surprisingly not have wifi, they for sure will have a internet cafe/any possibility to connect in their area, do some nice vsmalltalk to the girlies over ther(i hope you're male, lol) and you will get connected.
2nd:
BECTEL, that's the line i work on from home like right now at midnight, that's the same company we are connected to with free wireless at the Corner Bra at the plaza and several more spots in the area, call Charly(if you still don't know him let me know by PM and i send you phone numbers by PM), they offer several different speed connections for different monthly rates, i use their services since 4 months now and i am very satisfied with th eservices, not just for chatting on some travel bords, i run 3 websites and my businesses "contabilidad" online and it just works fine.
have fun
Mike
