April is an excellent time to visit...We went to ARK in April on a Fri last year...Hardly any crowds, decent weather. Then went up to the Creation Museum next day...It was a Sat, so a bit more crowded.
And there was a Groupon for a very nice winery near the ARK...I think paid $20 and got tastings w/cheese and crackers, 2 nice glasses and a bottle of wine ;)
I can’t wait to go!
