as mentioned in another thread:
shuttle service is inconsistent in and around Tunica and during some hours is not even running at all.
shuttle service from the MEM airport to Tunica is expensive.

In Tunica there pretty much aren't any cabs.

You are MUCH better off renting a car than trying to rely on shuttles.
Some people who have never been to Tunica before think it's going to be easy to get around. Then they find out they need to hitch or bum a ride or something just to get back to their hotel.

Rent a car. They don't cost that much and you'll possibly end up saving money compared with the shuttle cost from the airport.
