That is completelty unacceptable. I would hope that whatever room(s) that happened in were not charged at all and those individuals that had to deal with that and possibly the whole team should be compensated beyond a simple "no charge." Addititionally, whoever had a bad experience with malodorous rooms or hallways should be compensated to some extent as well. Finally, with no response from the staff there is some serious explanation and appologizing to be done on the part of the hotel managment.
As a paying customer, you should not have to put up with that crap, (literally

).
(sorry, couldn't resist the pun.) Actually, the team should make either an itemized list of the problems/bad experiences or a very detailed written monologue and present it to the general manager of the facility and first ask what he/she is willing to do about this. If the offer is not good enough, act disgusted and insulted and present your own. Nobody should have to deal with that, nobody.
EDIT: Additionally a report should be made to the Better Business Bureau. If they are a "recommended hotel" by a local insurance agency or travel group, a report should be made to them as well.
