Sanders delegate DNC convention

I have been elected as a nationalso delegate for Bernie Sanders. We are required to stay at the hotel chosen by the DNC, it is prohibitively expensive and the convention requires a 5 night stay. Like many Bernie Sanders supporters, I'm not wealthy and the expense is worrisome given that I will not be able to work that week either. Any unused funds will be donated to the sanders campaign or the campaign of down ballot candidates for congress. Any help you can provide will be greatly appreciated. In solidarity,
