This is a cool article about how to make the most of attending film festivals. Whether you're a pro like me or new to film festivals (especially if you're going to attend one for Timmy), this has good general information.
I have visited London many times, however, there were two occasions where I visited one time just before the BFI festival, and just after it ended. I need to plan to attend during the festival the next time I visit.
Palm Springs is my getaway playground. From Pasadena, it's only 1 hour 45 mins to get there. With bad traffic, it's double the time. I love it there. I would go to PS to watch the opening of a wall of paint drying. LOL!
the first time I attended PSIFF was in Jan 2016. I flew into PS from Michigan. I felt i was flying into a fantasy. The mountains and palm trees and the mid-century architecture is one of a kind. Old vacation Hollywood.
I never thought of going to the Palm Springs festival. I am a bit more of a commute away from there than you but not too much (wayyyyy closer to me than TIFF, ha ha). I've been to Palm Springs before, but it has been a while.
