Hi Paul,
19 already thats great reckon they'll be a few more before the date as its a long way off.
Have you been to the States before ?
Have you been with JY before ?
For me the answer is yes to both questions in fact Chicago at start of the route is my favorite city, stayed there many times, in fact once at the Palmer House Hilton which is a class hotel (although avoid the bar they knw what to charge, lol).
At time of booking it'll be my 6th JY trip but I'm thinking of doing a european trip before then so probably be my 7th.
Can't wait.
Mick.
