A. and I have made it to Athens.  Amsterdam was fun; we stayed with fantastic couchsurfing hosts.  They let us cook dinner for them on the first night (we did burgers with blue cheese and balsamic, with sauteed shallots) and they made dinner for us on our other two nights.  We did a boat tour, saw the Van Gough museum and Our Lord in the Attic (a Catholic church built among the attics of three houses while Catholicism was outlawed) and did a lot of wandering about.  It looks like we may have budgeted an extra day or so in Athens, but I'm sure we'll find something to do.
