My wife and I arrive in Frankfurt on a Lufthansa flight at 8 am on Sunday, Dec. 2, and plan to travel immediately to Nuremburg. It seems that we have three options:
1) Lufthansa Express Rail ticket. This is the least expensive and most convenient option, but we're travelling as Air Canada passengers and Lufthansa apparently will not sell us the ticket;
2) Buy tickets on the DB website. This is an economical approach and guarantees that we can travel, but we have to allow plenty of time (two hours?) at Frankfurt airport in order to be sure we make our connection; or
3) Buy the earliest available ticket once we arrive at the train station.
Any advice woulld be greatly appreciated. Thanks in advance.
