Unplugged 2018 Hotel Partners
Are you as late with getting a hotel as I was with making this post? Never fear! The hotel partner website is here: https://compass.onpeak.com/e/012604500/0
The hotel situation in Philly near the convention center is pretty great! Lots of very close options.
For paxen like east and west, the price break is SO MUCH that it's almost always better to book through the hotel partner.
If you're really on a tight budget you can get a hotel room in New Jersey that is cheap but it's a 15 minute drive. There's a subway that ends/starts in Jersey too you can take, but I don't know how stabby it is.
