Thank you for the input guys and in particular to Barklikeadog, I appreciate you taking the time to message that info.
As far as my background goes and specifics-
I should have a clear 7 days around mid-late February to visit Vegas and LA/West coast.
MMA background- I'm in my mid thirties and have racked up a fair few injuries (both shoulders and a knee) and trained in BJJ and Thai boxing in early twenties. I'm looking for one-off experiences (say rolling at 10th planet/ going to UFC PI etc)
Film interest- few years of acting lessons/coaching. Acted in various things but nothing worth shouting about. Written a couple of short film scripts (close to being commissioned on one of them).
As I'm only around for a short time thought it may be fun to see some of Hollywood (though heard negative things about it) and do an acting or writing class.
Sight seeing and coast lines would be nice. If there is sky-diving somewhere I'd be up for that too.
Vegas I figured I'd last only couple of days and cram in as much as I can. Just annoyed I'll be missing the AVN expo, haha. But not a big gambler or anything, the shows sound good.
Santa Monica and along PCH sounds nice and being English the cold doesn't bother me too much.
I agree that need to plan it properly so hopefully what I've said there helps with what I'm kind of looking to do. Thanks again for the ideas and please let me know if there is anything else.
