How much does the event cost, this will be different for everyone but whats the minimum you could attend this event with, that includes playing in the MW3 tournament and staying at the event for 3 nights
Depends on how many people you went and where you live, but on average I'd say about £240 without camping, £180 with camping. Baring in mind you asked for minimum, that would be: ~£55 for TUP ~£60 for hotel (Will probably be a 2man room for 3 people) (Remove this if camping) ~£30 Travel ~£100 spending (Dependent on how much you eat, drink and generally spend)
