Jim -
I played both earlier this month, and you can't go wrong with either course.
I loved the experience at the Dormie Club -- my wife and I were the only group that morning so we literally had the course to ourselves -- and the course is very, very good...excellent land, a lot of interesting holes and some outstanding greens. Plus the standard GCA fodder of width, ground game, etc. (An interesting note -- the club has a printout of Chip Gaskins' photo tour thread on proud display!!!)
But I'd still steer you to #2. Its current form is playing very well with an incredible combination of firm/fast, recovery options and, of course, devilish greens. Plus, the shock when comparing what you saw at #2 decade ago and what you'd experience in May could be cause enough.
All that said, I'd note that it's a ten minute drive from #2 to the Dormie Club -- even if you have only one day, why not try and play both?
