Graduation/25th Birthday?

Hi! I live in Miami but am having a graduation/25th birthday party at home in Baltimore - this is where most of my family/friends are. I've rented a small area of a bar for a nominal fee but overall the expenses of the trip are high. My celebration is really an excuse to get together with the people that I adore most and celebrate an exciting time in my life. I have to send invitations as there are a couple folks who don't check their email and I don't have a whole lot of time to call (17 credit hours and full time work to wrap up the summer). What I'd really like to do is send a "Dutch Dinner & Drinks" invitation and I'll pick up desert. How do I do this so it's not tacky? Everyone knows I'm coming home from far away - it'll be a very casual, laid back event. I've read on here how it's awful to do the dutch thing but I'm not sure I have any other options. I can't use someone's house and picking up the entire cost is unrealistic but I want to see everyone & won't be home long.
