I go to Disneyland as it's really the only theme park I get a chance to go to in general (never have time to go to ones in the UK) and I suppose its really my backup event, I know where it is, I know I can enjoy myself there. But you are right, it's easy to can the visist if I find something else
Hence this post for ideas
Kyoto isn't really an extended option this time as i've already paid for my hotel in Tokyo and being Scottish the thought of not spending a night in a hotel i've paid for...*shudders*, but you've kind of reinforced the point that it might just be a waste of money going for the single day.
So still open for feedback and advice
