Could someone please tell me the hours of water taxi service? and..how reliable they are? We have friends staying across the river to the north and would like to travel across at will from Del Rio or another hotel. Is this possible at all hours of the night? thanks

here's a schedule, it may not be the absolute latest, but it can give you a good idea...

many of the places up north have their own boats that come to town, but not at the wee hours...
