There are also a couple cab companies but I'm uncertain if they'd be willing to deliberately get stuck in traffic for a measly $6. This is an old post but in case anyone comes across it and is looking for an answer.the outdoor venue is not covered. A bunch of the local hotels offer shuttles to and from the casino, strongly recommended if you want to drink at the show (we have at least 5 different types of cops in Mt P). Plan on spending at least an hour stuck in traffic when departing, unless you leave a good 30+minutes before the end.

I would recommend arriving at least 1 hour before the show to avoid the inevitable cluster f*%k. The concert area has its own outdoor parking area (potential deep mud, hence the socks). It's a good walk to the casino parking lot but disable. A poncho and spare socks+shoes are recommended, esp if you're parking there.

Depending on you and the show it CAN be fun in the rain (ex. I recommend sunscreen as well as some other protection, such as a beach umbrella or parasol (sitting in the sun for over 2 hours in 90° weather is brutal!). For the summer concert series all the seating is open air.
