I am trying to throw a relatively classy party for my brothers 40th birthday at a hotel in downtown boston.  I have spent hours googling, trying to find a hotel that might lend itself to this.  I am looking for a suite which could fit 8-10 people hanging out and we wouldnt be too out of place if we were (only) a little loud.

It would be on a thursday night & we are willing to pay- but I just have no idea where to start- do any hotels have a rep for this or maybe even cater to such events.
