To party or not to party?

I'm facing an unusual dilemma here. Our company has received an invitation from our partner company to their Christmas party, and it's been suggested that Hubby and I fly down to Sydney at the end of November to represent us there.

Aside from the ever-present problem of my likely state of panic towards the end of NaNo, a more worrisome aspect of the entire venture is the invitation, which goes as follows:

just to let you know the Xmas party is on a Tall Ship Svanen, leaving The Rocks at [date and time removed to prevent gatecrashing]

bring yourselves ready for a goodtime, the usual booze guns pirates swimsuit models, massage and bikini girls will be onboard

Um... riiiight. I'm not usually much of a party girl, mainly because of the whole extreme introvert thing, but I don't think I can really justify missing that. Just for... well, for just for the sheer experience of something so mindbogglingly politically incorrect!
