We will be visiting the Biltmore in June. We can visit on a Sunday or a Monday. Which would be the best day for crowds? I have an 11 year old girl and a 16 year old son. What activities should we do? We will be able to arrive around 9:00 am. I really want to be sure to make the most of this visit. DD is an equestrain so a visit to the horse barn will most likely have to be on the agenda. She will not be interested in a trail ride as she is a jumper and that would be a little boring to her. My son want to do a seguway tour. Would we have time? Can my DD go on the seguway tour? Thanks for your help.
