This page lists the rental cars available at the airport (I think). I know at least Hertz and Enterprise have locations there. They are showing about $100 a day at the airport locations. However, if you uber yourself from the airport to say, the 41st and Memorial location (or otherwise arrange your transportation), the in-town locations are showing about $70/day. Just sayin!
This is right next to the venue. It's walkable but not an ideal walk in the dark, since it's out in the country. All the cottages have lakeside views and are very cute!
This is the "getaway" option. You cannot uber around in this area (at least, not easily). You may want to get a few groceries and bring them to your little cabin if you are staying for several days, but there are also a few restaurants/fast food joints in the area that you can drive to.
This hotel is 40 minutes from the venue. However, it is very close to the local Brocks and the highway. This is the "I want to stay in a regular hotel with breakfast and full accommodations" location. It is not the DoubleTree in downtown Tulsa. It is fairly close to the location of the rehearsal dinner.
