Question about the Art Car Parade

I just booked a MegaBus ticket to come from Dallas to Houston for the Art Car Parade and I'm planning on buying the VIPIT ticket. The bus dropoff is at 815 Pierce St and the location for the VIPIT experience is about a mile away, which is a little too far for me to walk. (Moderately mobility impaired.) Will I be able to get an Uber/Lyft around noon or will street closures and such make that a challenge? Any other advice? This looks so fun I just had to do it!
