Lots of different girls tour Stevenage. Hotel in the town centre mostly, I think, or the one by the A1 junction. Trouble is, Stevenage town centre is a bit gutty these days, I think. Chav Central.
I would imagine MK would be a better bet for variety and quantity of choice. I tend to look more in towards N. London. Easier to get to than MK for me.
