Hi,

I started the eurailpass thing after I was 26 (heh I was an adult
college student too)... so I had to get the first class passes...

I never did the supercheap live in a backpack with an unlimited
eurailpass sleeping on the trains every night thing.

but I've done the 5 day flexipasses several times successfully (that is
to say it was a better deal than buying separate tickets).

I'd do an Amsterdam>Munich>Florence>Paris>Amsterdam or an
Amsterdam>Paris>London>Amsterdam... and in those days (not to long ago)
there was still an overnight train with couchette between Amsterdam and
Paris (last train out of both) and I'd do most of the jumps as
overnights with couchette (and I was entitled to a 1eme class couchette
where they existed... I got a 3 person sleeping car from Florence to
Paris) so the overnights were really pretty comfortable.

what I've never done, and a eurailpass gives a discount on, are the
ferry's from france <> ireland... that I want to try.
