Thanks for your reply.
However, if we did park at the TTC at 7.30am and then get the monorail to MK we would not have a lot of time to enjoy the slow walk up Main Street without the crowds.
Therefore, is it possible to valet park at CR at 7.20am and walk to MK and wait with our noses pressed up the turnstiles until they let us in

I know that this is VERY early but as this will be our first full day of our holiday we will still be in UK time.
We plan to leave MK mid afternoon to get some rest and then head back later in the evening.
As I have said before, we are not looking at "working the system" and are more than willing to pay extra for this service.
Thanks in advance.
