Cleavage or No Cleavage - That is the question

So I am off for 8 glorious days to travel with my family, which includes approximately 15 of us (no, it is not what you think we are not polygamists). My small 4 person family will be joining my husbands ENTIRE family for a cruise.
Yes, before any of you ask, I did refill my "I will not notice a damn thing" and "it gets better and better with several glasses of wine" prescription. Thank god, and whoever else I need to for that!
Here's my conundrum if you will...apparently all of my swimsuits are designed for maximum cleavage, I love wine, family for 8 days, I love wine, two children, I love wine, and well, I love wine.
Why am I worried you ask? Well, my in-laws, are all MORMON. They do not drink, they do not have, I mean, condone even the remote sign of cleavage, let alone sleeveless shirts. They are a however a witty and humorous bunch, and now that my sister-n-law came out of the closet, which completely rocks by the way, her girlfriend and I have been coming up with our lists of drinks for maximum entertainment for both ourselves and the family.
Now just so we are clear my husband, who is also very witty, humorous, hot and my partner in crime, loves wine, and definitely loves cleavage, is a return missionary, another thing I have in common with dooce so no problems there. Amen!
So I am sure to have some incredibly entertaining stories upon my return. Because with the meds, wine, and our daily prayer, there is no chance in hell I will touch the internet.
Stay tuned...
