Bachelor Party: Where to stay?

Hello everyone,

I am the best man in a wedding in October. Looking to come to Charleston area for the Bachelor Party. Not looking to spend a ton of money on a location to stay. We have 7-9 people coming. Everything downtown Charleston on AirBnB and VRBO requires either a minimum stay longer than ours a for August 8-10 or is pretty booked. Any better place to stay in Downtown for around 300 a night? Can we still have a great time if we stay in Folly Beach or Mount Pleasant? I do not know alot about the area. Looking for bars, good food, and things to do during the day. Any suggestions would be great. Thanks!
