Any recent experiences w/ Colonia Express boats? How are the boats? (Travel time shows 1:15.) How much anticipation time in both ports prior to embarkation? It looks like they are single class w/no expedited / comfort seating (which was handy on the Buquebus for later port arrival time).

(For those unfamiliar with the current state of affairs, Colonia Express is located at the far southern end of Puerto Madero, near the casino, and is a short walk from San Telmo. Buquebus is located essentially on the northern end, around a huge construction mess for the next year-plus, until the new truck bypass highway is completed.)
