Hotel parking is gated, so you will not be able to use it. However, the office complex right next to the hotel will have tons of parking available so just park over there and walk over. To get to the parking you will want to turn onto Amphlett Blvd Toward the freeway. This will take you around to the main entrance. If you drive past the main entrance you will see a little sign that says "Grapevine Cafe", Follow that arrow into the parking lot and you can park there.
We will actually be meeting and playing in the lobby area. So, after you come in just look for people playing games.
