^ Thanks for all the advices !
The big reason why I'm so keen on getting to x2 first is because you need to pay to use a flash on it , and as the flash pass has no limit , I was thinking of using it later on.
As it would obviously not be smart to stand 2 hours in line for x2 when I could also run for it first thing in the morning.
( I've got the stamina to go very , very fast so that shouldn't be a problem )
Though afterwards I'd now probably go straigth to terminator/batman/riddler/goliath , and then pickup my flash.
Just confirming , but is the service centre at the entrance really the only place I can pick it up ?
Yet again , thanks for the advice , and I think I'm really going to enjoy my first sfmm visit !
