Ok folks had a bit of luck on the hotel front.

After struggling to get through to the Marriott again we started looking around once more for alternatives.

Hotel Details

I've been in touch and they have actually hosted car events on their premises before so they're very understanding and welcoming and have outside water supply and power that we can make use off. They have 65 rooms and suggested booking through their website as it's usually cheaper than booking via Booking.com

They're just along the road from the Marriott so slightly closer on the drive down and not much further to drive on the morning of the show.

I'll also add the hotel details to the first post.
