Morocco
It is definately worth investigating hiring a guide to go around the souk with you in Morocco. Not only will you get less hassle from the sellers but you can avoid getting lost (it is a maze) and also benefit from their local knowledge.
Be careful as most guides will receive a commission from stall owners for bringing tourists, but don't let this deter you.
Preferable if you are female.
