We’ve just been Monday and Tuesday and made the mistake of arriving at 10am first day and not really having a plan. Second day we did much better and arrived at 9am, on first monorail into the park and headed straight for the Smiler. It’s queues were the worst all day, so good to get it done in 40mins. The wicker man would be another good starting point, even shorter (dh headed there with our youngest as he’s too small for the smiler).
Nemesis and Galactica weren’t too bad for queues later in the day, and watching the app we got on Wicker Man, Thirteen, Spinball Wizard, Runnaway Mine Train and Congo River in between 10 and 40 mins. I don’t think you would need fast pass for Congo River as between us we did it 4 times without much of a queue. Rita always seemed long, we went to it second with the queue time showing as 15 min, but it was more like 50, and we didn’t think it was worth it. We did bite the bullet and queue over an hour for Oblivion, which was a favourite. If I’d known we could get a fast pass just for it, I would have done it!
The queues get shorter in the last hour and ride queues stay open until closing time and continue until the whole queue is done. Our first day ended with Nemesis and two goes of Glactica with no queue and they are right by an exit to the car park to save on a wait for the mono rail. You could plan to do one of the biggies at closing time if there’s one you haven’t got on/ couldn’t face queuing for.
There are free water fill stations. 10 doughnuts for £7.75 were good, but we took a picnic to save money otherwise, so can’t comment on food.
