My husband and I went to the Disneyland Park for a day last week, and contrary to our last trip, I actually managed to edit the photos AND get the blog post up in good time
So for those interested, my trip report is here: here 
(I tend to chuck in a ton of photos, so I rather link to my blog than clog up the forum)
Nice report as always.
Looks like you had a great day, even though you had a rough start in the morning.
Regarding sat nav, if you have a smartphone, one idea can be to use Google Maps to navigate. I use it, and I think it's easier to use than TomTom.
You might have said it in your report, but how was the crowds in the park? Doesn't look too bad in the pictures.
