Appreciated, and while I'd never presume to tell you how to spend your money, understand you're up for a very long day in HQ. Stack the deck as best you can, Recruiting will Give you a list of hotels close to HQ -they're on the same block.
Get a good nights sleep and walk over.
It's an early start; I was first in the door and had a full ten minutes to chat with most of the days recruiters.
A number of people in my group couldn't make it home that night and stayed over... like I said, its a long day..
good luck..
