We will be going to the Paris Olympics and would like to do a day trip to Giverny one day. Our only completely event free day is a Sunday; otherwise we can go on a Tuesday or a Friday (when our only events are late evening). I read in Rick Steves' Paris book that one should avoid Sundays for a day trip to Giverny due to crowds from cruise ships that day. Does everyone agree with this or are we just as well off going on Sunday since it's our only completely free day? We'll aim for the 8:15 am train
Related to the train, can I just buy on the SNCF website a few days in advance?
Thanks!
