My last stay at the Flamingo a very nice BJ dealer told us that if we were going to the airport, we should take our luggage to the Quad's valet and get on their direct shuttle to the airport. They claim all the other shuttles make stops to other hotels which can be a long delay. Anyway we did this (kind of a pain walking the luggage to the Quad) but it did exactly what that dealer said. Straight to the airport with no delays. It was the best $7 spent for the whole trip.. Only problem, the valet said it doesn't have a schedule for it just goes back and forth from the airport all the time but we only had to wait 10 minutes at 9:30 the morning.
