Caen is really the only option.
I would do a trip to Goodwood, the I of W, or some where like that on the south coast if you are in any doubt of the leg to the coast before.
There is plenty on here about flying across the channel - well worth a read. If you have never done so before the most noteworthy aspect is you can find yourself pretty much on instruments even though conditions were good or reasonable VFR over the land.
The short hop in France is a non event.
Closer to the time you will get plenty of help from those on here if you need more information.
In summary use the time between then and now to either make a hop down south, or even make a run across to L2K in the spring. It will give you all the confidence you need - if you need it. However, the trip should be well within your ability.
