BrummyGit
I am not at the business end of things and I would never condone lying. If you are able to convince Mrs BrummyGit that for example:
"Virgin agreed to look after it"
"It won't cost anything near that" (having contrived to make it seem even more expensive)
"We have come to an agreement"
"It's worth it to treat you"
In essense, not lying, but being economical with the truth, you may in the meantime attempt to gain some clemency from Virgin - as unlikely as it would seem.
To have Mrs BrummyGit feel at ease must surely (I say with temerity) be worth it.
The alternative is to downgrade yourself voluntarily, which, if you are unwilling to be devious or stump up, appears to be the only option. The 200 GBP can be spent most productively when you are there!
In any event, please don't let this sour your trip.
