Right just heard back:
Gibraltar Neanderthal Caves and Environments:
The 9th is a Saturday, which is possible, but we'd need to pay for the guard on the gate (they don't work weekends or after hours) and would ask you to reimburse that cost (not sure how much but not a lot), and I need to check who is available to guide a tour. I know that at least three people are away, but I will check and get back to you. I don't suppose you could manage the Friday?
The other thing is that we may have to cancel at short notice – weather possibly or military requirements – of which, of course, we do not get advance notice and over which we have no control.
So just quickly, is the Friday an option for people? (I imagine no is the answer, but I have a touch of flexibility myself so perhaps could do it)
Also just to flag up that there is a chance of a last minute cancellation with no notice, so if we did want to go ahead then we should perhaps keep this in mind and perhaps have a contingency plan?
