I don't mind the extra 3-4+ hours.

As long as they get us there eventually.
Right now, if we can save $30 bucks here or there, that leaves $30 for something else. Putting up with extra travel time, or with a less than ideal situation is easier than coming up with extra money (although it would be nice if the opposite were true!).
But I may not even have to worry about this. Hopefully I can find a good deal flying into Puerto Plata instead of having to go with the buddy pass option into Santiago.
Thanks everyone.
