We are going here this time,I just took the plunge tbh there wasn't a load of choice left for this year, but I did find quite a few nice ones along the way for another time if it goes well, best thing to do is email them and make a judgement on the replies you get I guess

As for the roof box I got quite lucky my neighbour was taking her kids on hols and had hired a roof box, I just phoned the guy and discussed what size I would need, and he happened to have a large one they use for skiing fits skis I think it's a thule (alpine) also, and checked the length was OK,
I am buzzing tbh, can't wait just got to sort out all the details now like insurance, car stuff, passports, Channel crossing you know thr boring stuff 😂
I did message about bait last night though so hoping to get that sorted soon 🤔
