Quality, fresh tulips should hold up with no worry at all. I would wire and tape about 2 inches below the head so they can be moved without braking the heads. Gather the heads up very closly and tightly, don't leave alot of stem exposed at the top (just under the head) as they will start to droop and fly away as they warm and open. The tighter the bouqet, the better they will stay in the propper place. Also, spray with crown and glory and cover. Put in cooler and keep out of the light to keep them from growing after the bouquet is made.
