I know for many the canned answer is the magic but if that's the case then just go to a magic shop. I mean what makes you go many, many times a year.
For example, I go because it's a wonderful few hours with my mom. No stress, no job, no worries. Just me and mom. I have gone by myself but it's not the same.
I used to hate Disneyland and loved Knott's. Again it's family time. Used to take my nephew a lot for about two years but then he came down with a terrible illness. BEING A TEENAGER! Well that and a very tight schedule. Honers in school, diving, learning three musical instruments... that kind of thing.
What's your deep down reason for going?
