Boy, you asked a loaded question about whether to put the plants through dormancy! For this time of year, the opinions are diametrically opposed. One person even said that he wouldn't buy a plant at this time of year! Now that I've just scared you, be prepared for a potential debate.
I have purchased CP's, the dormancy types from Home Depot at this time of year. I kept them at a SE window sill (drafty) at the lab in which I work. The temps got as low as the mid-50's and the photoperiod naturally declined. The Sarracenias I let stay on the sills. the VFT's I ended up taking them home and put them through a convoluted process of trying to get them cooled, but not frozen. I had them between the storm and inner kitchen window - but they got "greenhouse effect" on sunny days. I was told to get them colder. So I put them in our screened in porch, where they were okay until a cold snap froze the soil. So I moved them. as is, to the butter keeper of our fridge. (Can't believe my wife tolerated that maneuver!) In February I moved them back to the lab, into a sample fridge, for awhile. Then I put them back on the drafty window sill to gradually warm up. Then it was outside and by April, I was rewarded by flowers. The Sarracenias didn't have a proper dormancy, but when I put them outside in the spring, they responded and I realized that those 50 cent rack plants I thought were S. rubra - turned out to be S. leucophylla of some sort.
I wish I could tell you what the plants you purchased are expecting, where they are on the yearly cycle. If it were up to me, I would keep them where they will have natural sunlight, be it outside in some safe place near the dorm, or a coolish window sill. I wouldn't toss them from 70 degrees into a 40 degree environment, but I would gradually move them in a less lit and cooler direction. Disclaimer: This is just my opinion. There are others.
Um, there are MANY generous folks out there that would be happy to send you window sill plants, that don't require a dormancy, if you're interested.
