Agreed, but I wouldn't do le Touquet on a nice Sunday, unless arriving before 10am. The place fills up with Brits, some of them unable to fly never mind make radio calls, and it can get a bit scary for someone new. Weekdays are completely different and highly recommended.
Special Branch is for CI, Ireland (N&S) and the IOM, only. 12hrs advance notification, preferably by fax.
There is no need to speak any French if going to/from an international airport, which one has to do anyway unless flying within France.
