Hi, and thank you.

Burbank is definately not an option, as the flight has already been booked and paid for, and is non-changeable.

However, I might actually consider changing to a different hotel for the last night! Searched Hilton.com, and found some ok rates at one called Embassy Suites Los Angeles Airport North. I think that's where we're staying. Thanks!!

However, how much time at the airport do you think we will need on a Wednesday morning?
