I'm planning my first rail trip in awhile, and my very first long distance one. From the SL, I'm trying to fit in the CS, CZ, and EB, all in one trip, if possible. I've been reading on these forums, and I think I heard this right, that it would be best to take the EB eastbound, then, since I will have a sleeper, I get wine and cheese tasting, and trivia contests, am I correct? My main concern is, how busy does this route get in the summer time?
