The tunnel is a breeze. Arrive at the Folkestone end and go through the ANPR entry system that recognises your MH registration and will automatically give you your boarding ticket. Although it wasn’t working 3 months ago (Covid perhaps?) and the ticket was being done manually. If you arrive a bit early you may sometimes get given an earlier train, bonus. Then if you have a pet you need to pop into the pet reception to get the paperwork verified.
Drive to the waiting area and park looking at the large display boards showing, clearly, the train departure times, and how long until your ticket letter is called. Once it’s showing allowing you to board you then drive through to the first border control, passports etc., then get shuffled to one side to ensure your gas is OFF. 100 yards and through to the French border control, passports at the ready, see if they ask for your Covid pass details - I wasn’t required to shown anything, just a grunt “double-vac?” And we are through.
Follow the signs and drive down and be directed into the side of the train, it may look a bit intimidating at first until you realise it actually is really wide enough. If you are first in the queue it feels like you’re driving to France as you are going down to the very front. First in, first out.
Park where asked by the attendant, handbrake on, engine off, windows down a touch (this is a chunnel requirement) then get out of your seats and make yourself comfortable on your bed/lounge and relax for the next 30/40 minutes. It’s a very smooth ride and you barely realise you’re moving or stopping. Once you are permitted to exit, remember to drive on the right.
When you get a free moment, you will realise it is soooooo much simpler and easier to travel compared to the channel ferries.
