When you had money and were creative you could make parties happen anywhere. Blair had both money and creativity in spades, and thus her party was born.
It was an Antarctic theme so there was ice aplenty. Blocks of it were used to make tables and chairs (with blankets and cushions on them - Blair would suffer for fabulousness but there was no reason to willingly give yourself frostbite). Slabs of ice made up the bar and the tables for food. Carefully placed lights helped to show off what was available. All in all the end effect was something not unlike
this. The only thing that wasn't as icy was the floor, because much though Blair would find it amusing to watch people fall down, it ran the risk of her pretty decorations being destroyed.
There was dance music playing and a space for dancing if anyone was inclined. There were plenty of extra blankets for anyone who hadn't dressed warmly enough to avoid a chill, or just wanted an excuse to cuddle. There were also tables set up in booth-like formations for those who wanted to sit and chat without being in the middle of the flow. One table had its own bar, extra thick and comfy pillows on the chairs, and luxurious blankets to help stay warm. No prize for guessing that this was the table Blair had claimed.
