Specifics

Okay so I was reading and I guess at a lot of places you can preorder tickets...for example the Louvre in Paris. With preordered tickets you do not have to wait in line. Does anyone else want to go there? Would this be of interest to us? Also I found the night train route from Krakow to Prague,it leaves Poland at 10 and gets into Prague at like 7 in the morning and its non stop, we cannot purchase the tickets online, at least I haven't found a place to do that yet. I also looked into Edinburgh to London going to cost us around 80 bucks a head. Getting jacked up here in La Crosse!!!
