> So if you say vacation, you better show hotel reservations from start to finish dates, return ticket and all.

I have no argument with the return ticket. Most countries insist that you have a return flight as a condition of entering.

But having hotel reservations for the entire duration is just ludicrous.

I often travel to places for which I have a reservation at the destination for a couple of nights and then take it from there.

Going to Japan for almost a month with a 3 week JR rail pass makes it just about unthinkable to have the entire journey planned.

So, I guess, no more US for me. Not that I'm currently tempted.
