Our family of five - two adults and three teenagers - will be taking the night train from Vienna to Venice in June. We have eurrail global passes. My question is about accommodations for five people. Because of price and safety (we would all be in the same room), we would like to book a couchette. How have people done this with 5 people? We would really rather not have some random person sleeping in the 6th bunk if that's possible. We are friendly, but it seems weird with just one person. I have researched this (I have scoured the seat61 site in particular because his tips are so thorough) and I can't find many solutions. Some that I've found are:
1) Book a 6 bunk couchette by paying the reservation fees for the five of us and buy a ticket for a ghost on the 6th bunk.
2) Book a 4 bunk couchette, assuming that 4/5 of us will be placed in a room together. The 5th person can sleep on the floor instead of their assigned couchette.
3) Book a 2-bed sleeper and a 3-bed sleeper and hope that they are near each other.
While I am at it, what are general opinions about which site to book our reservations through? I'd like to book these as soon as possible.
