What's your budget? (Am I allowed to ask that? If not sorry!)
We have a small budget, yes, less that's $200 for a semester small.
We do a lot of stuff though. movie nights are fun, but don't work well with conversation.
one thing that works well on our campus is figerpainting and crayons. who doesn't like to draw! agian, we have a unique campus so that might be why but we do fingerfood and stuff also.
one place for ideas is
www.residentassistant.com it is for RA's but they have some great ideas that you can do for a reasonable price.
We did kareokee (sp???) we had the machine and just hooked it up it was easy! and everyone had fun! you need to have reallyout going girls who will start it and then it is good!
Good luck!
