Don't forget we have two extremely competent mechanics at the workshop (Scope and Nat_P) so you shouldn't worry about the time it will take. Scope can be doing his hoist thing (he loves that) while Nate_p will be there to help out with whatever comes along.
We can provide tools, etc; ( I will bring my socket sets, etc; to help out as I am sure others will) and the whole idea of the day is to get it get some of these types of issues sorted out, while giving people the opportunity to learn about the possible trouble spots with the cars. Check out the photo below from last year.
Even if you can just confirm or deny the problem (that's like "aware but not anxious"

) it will help to reduce the time you might have to take on your holidays to fix it properly. As happened last year with someone's SW20, you might find that what you think it is most certainly is not the case.
