As a 100K mile per year flyer, I can say in all sincerity: roll don't fold the suit. If it still comes out wrinkled, any decent hotel will be able to have it steamed for you on short notice.
Bundle wrapping is great, I've done that for a long time.
Before that, I would 'Roll' my suits You get less wrinkles that way.
Any wrinkles I did get were solved by hanging the suit up in the bathroom, and letting the hot water in the shower run for a bit. 'Steaming' garments in the bathroom works really well. Just go in there after about 30 minutes, and pull down on your garments, then let the bathroom air out. (And the clothes to air dry.)
I would suggest wearing the suit.
