Not the best experience I've had with a rental company but was not the worst. Bus pickup at LAX was good considering it's LAX. Since Dollar and Thrifty share pickup bus, we were second stop. There was nobody at express office and after waiting 5 min in the sun, went inside. I noted not many cars in lot. After getting in regular line, took 20 min to get to an agent. I got my paperwork done smooth though usual upsale on pre pay gas and insurance which I had already indicated in reservation I didn't want. Went back outside, agent took paperwork and inform me no midsize, wait inside. Some 30 min later another agent asked if needed something. She went back out after I told her I was waiting for car. She return with news that outside agent didnt have paperwork and asked if I had done it. I went to doorway, pointed at the agent that took paperwork. Brief discussion between two and I was taken to express desk to do paperwork again. She informed I was going to get an upgrade for the mixup, a midsize. Wait thats what I had...no you rented a compact. I was now thinking "just get me a car". Waited 10 min and was on way out. Whole process from pickup to driving out 1 hr 40m...way too long. Car is nice..15,000 only it. I will think again with going with least cost rental company, never had this with budget or avis.
