The car parade is at Old Town on the 192.
It is lively at weekends and they do have classic cars on parade in the evening and on show also. Midweek can be quiet and not really worth the visit.
People have mixed opinions on OT, some love it and others hate it. It's certainly different to anywhere else in Orlando and not really something you can describe easily. There are some very 'unique' little shops there and it does in a way have a fairground type of feel also.
We have had some good evenings there and I know John always likes to sit at one of the open outside bars and people watch - always gets talking to and meeting interesting people.
For some reason we hated it last time we went, I honestly can't recall why.
