Is it expensive to go on an externship? I figure with travel, hotel stay, and meals for 2-3 weeks that it could get very expensive. For those of you who did externships, how did you afford this? What did some of your externships "cost" you? Financial aid doesn't budget for externships to my knowledge, so did you have to save up money to be able to do this? Just trying to plan for the future. Thanks for any help.
