I'm a naturally fast walker - I have always been the one ahead of everyone - and that is everywhere, not just at Disney.
Telling me to slow down to my husband's pace is like telling me to change the way I talk. It is in my nature, has nothing to do with Disney, commando style, vacationing or anything. It is just me.
My DH walks very slow. He eats very slow also. He just does everything slow. I don't tell him how to walk and eat, he doesn't tell me.
However, if I hold his hand we do walk at the same pace.
To the OP - if you want to keep the pace the same more, hold your husband's hand! And if you want to go a little faster, just start walking a little faster - if he is attached to your hand, he will speed up without knowing it. Find the happy medium that way. If you are not holding hands - then you each go at your own pace!
And to all of you who say slow down - I say nuts to you! Just as hard to slow down as it is to speed up and there is nothing wrong with walking fast. Why do al you slow walkers always see it that as something wrong with how we walk? I see everything I want to see and more. If you want to walk slow, go ahead and do it, matters not to me, just no disparaging remarks because I choose to go faster.
