The holidays will have started for some by Monday. However if its the same as last year where the schools around Alton have a different holiday time, then it'll be quiet :DEven if it's busy, as someone said, you don't feel it the same as at other places because everything is so spread out. As well as the majority of rides being good at getting through the queues. (Sonic Spinball being the main and only exception that springs to mind.)Basically , if the schools around Alton aren't on holiday, I'd expect 45 mins max for Spinball, Rita and Air. An hour for Thirteen at opening but that'll come down. If they are on holiday, I'd assume 100-120 mins for Air/Rita/Spinball. Possibly that much for Thirteen at opening but that would also come down. About 60 mins for Nemesis and Oblivion. This is just from experience
