I would definitely recommend that if you want to do the Blagaj, Pocitelij, Kravica typical tour from Mostar do it with Philip and his dad, good people and reliable, they were also very flexible with pick up and drop off. Me and my girlfriend rented one 50cc and manage to do the whole tour for less money, freedom and fun than a organized tour. It's very feasible to do it in one day and anybody with a bit of experience on a 50cc can do it, don't if you've never being on a scooter before. But still traffic is not very heavy and the scenery is beautiful.
