From the self-park you end up on an escalator down into the walkway between Paris and Bally's - as mentioned for Bally's you go to the right when you get to that walkway. You can go to the drop off and then circle around and there is a drive between two buildings and then a left turn (away from the strip) takes you up a ramp directly to the self-park. I often will go to that entrance to drop off people (certainly what you would want to do on arrival with your bags) or pick up people (again for sure when you depart). If you do self-park it is important to understand that you can access the self-park directly from that same main front entrance. The side entrance off of Flamingo is just for shuttles and ride-share (Uber/Lyft). It is just located in the main entrance behind the Bazaar. Shuttle is the best way to go Plus it parks right in front so you can easily check in. Re: transportation from airport to Ballys. then Uber, then taxi, then walking, then bus. Valet is very convenient (and free for me as a Diamond member - so cost is just the tip). Next- Stretch limo (Very affordable, you might be surprised). Good place for stay in the night, close to flamingo hotel and casino, we. Sometimes I valet and sometimes I use the self-park. there is a sign with parking rates in the lot. We have stayed at Bally's several times - and usually have a rental car.
