I have a multiple entry TR visa from the US that I will extend 30 days tomorrow. I normally enter with a retirement visa. This will be my first border/visa run.
My priority is cheap and quick but failing this, enjoying my time is priority.
Flying out in the morning and back in the evening is best. Who doesn't like sleeping in their own bed? but not necessary.
Flying out in the afternoon, spending the night and flying back the following morning is also okay.
Ground travel might be okay as long as i am not spending many hours in a crowded bus, van or car. A train is an interesting idea and i might spend many hours on a train if it proves interesting or a land border crossing is somehow better.
So, let us hear some ideas...
