Thanks for the info.
I will be arriving around 11:30pm.
So its not TOO late to drive to Ontario.
I went on mapquest and it seems it is about a 45 minute drive.
I have 2 Marriott certificates (up to cat 4) that I need to use by Sept, so I figure this will be a good chance to use one.
Probably - Residence Inn Ontario Airport, unless you know of a better Marriott that near 15?
Thanks
