Hey all, I just wanted to pop back and say thanks for everyone's advice and input. I was at Movie World on Monday.
Had an absolute blast of a day, and had no issues with my bag. Locker for Superman, but everywhere else was fine. Queue times weren't too bad, although if I had a do-over I'd probably get a fast pass to skip some of those 30 minute waits.
Had a blast with my camera too (off-ride, obviously - I love my landscape photography, and rollercoasters - duh - so was great to have brilliant conditions for that too)
Just a big thanks for everyone's input and suggestions - made heading out solo much easier knowing what to expect. And now I want to come back and do it all again
