Does it really matter what someone else calls them? If you're content with the price you're paying, and you've arranged the trip to get the maximum number of miles, then you can call it a MR. Some people on here won't agree, but they're not the ones taking the trip - you are!

I've flown to several destinations (BNA, TPA) where I wanted to go to see friends, and just booked myself the long way round (eg, LAX-SEA-ORD-BNA/TPA) to earn more miles for a minimal increase in price (but still a good cpm rate in my opinion). I only stayed 1 night in each case. I've called those MRs, as I have called flying to/from MSP (on a fairly standard routing) and turning back around within 45 minutes. A MR is what you want it to be!
