I have a Dahon MU P8 that I've been on 75 mile ride with. Most of my rides on it average around 30 miles. I'm 5'5" 150 lbs.
Packing it for travel takes about 20 minutes on either end of the trip. I don't do much to protect the frame from scratches which saves some time.

I'd also recommend test riding a bike first if possible. Also check out the suitcases. My wife's case is different than mine and so the bike fits different (same model as mine)
