Glad you asked...yes I was thru there yesterday and was going to post my experience!
When I completed it online the only paperwork I got was a receipt for payment ...I was supposed to get an actual tourist visa looking print that had all the details filled in. I did not get that. So after trying to explain that to them I had paid but had no visa printout,
I ended up paying for a new one. It's 332 pesos, so make sure you have the actual visa printout and the guys there will stamp it and your on your way.
I'll try next year, as there were a few rigs going thru and if I'd had all the paperwork I could have sailed thru.
Tony the guinea pig!
