Overnight near Calais with four adults and a 2yo?

[BabCNesbitt]

DH needs to leave the country for one night to get his work visa stamped when he re-enters, and my DB has suggested that we all get the ferry over to Calais from London for the night (out Saturday, back Sunday). It would be me, DH, DB and his BF, and our 2yo DD. Is there anywhere near Calais that would be worth visiting for a few hours and a possible nice stay overnight?

LeTouqet is lovely and less than an hours drive from ferry port

That does look pretty, thank you!

(And I sympathise with your username... )

If you are on a budget the BB hotels are perfect for a short stop?
