I'll be flying into Montevideo in June due to an excellent fare from American Airlines. I'm thinking about taking one of the boat trips from Montevideo to Buenos Aires for a couple of days. I understand that if I fly into EZE or AEP I would have to pay the reciprocity visa fee in advance. It's not clear to me if I need to pay the fee if I come into the country via boat.

Does anyone have any current information on the visa fee when arriving by boat?
