I am in the early stages of planning a twin centre US trip for next year. My initial plan is that the first week will be in Orlando. My children will be 11 and 9 but they’re not hugely into Disney so I’d like to do just 2 park days - one epic MK day and maybe Epcot (although I haven’t researched the second day properly yet - second park would be whichever had most Frozen/Moana/Encanto). Can I get really simple 1 day, 1 park tickets rather than have to get the 7 day Magic Pass. And if so, how early can I buy them or does it have to be on the day?
