Depends on the ladies in question surely?
If they are indeed girlie girls who like their home comforts, then B&B is indeed the best option!!
However, if they are like me, love flying and don't mind roughing it occasionally (two nights is hardly a major hardship), then go for it. Any female who has half a sense of adventure will not mind forgoing her hairdryer for a day, make up, mirror, straighteners and whatever other paraphanalia she needs!
Anyway, i'm sure you'll be very popular, not many chaps can offer a girl a free flight in a light aircraft...... Put it this way, a date in the Local or three days flying over beautiful scenery at 2,500ft...well, for me at any rate that is a no brainer...but thats maybe co i'm a tad biassed being a female pilot (well, ok, student pilot then!)
Good luck!
