I am currently on my program taking 4 online classes from my university and one seminar class from Disney.
I'm in Disney heritage right now and although I've only had 1 class, I really enjoy it. It's just a lecture class so no homework or anything, we have a great time, the teacher is fun and we will even be having class at Studios and MK one day. Lecture classes are about 2 hours long one day a week so choose what you will.
As for online classes, if you can help DO NOT TAKE ANY. I am now in 4 classes (one graduate) that I had to take to retain my scholarships and full-time status. Only one counts towards my degree and I didn't realize when I enrolled that one was a graduate course. It's extremely stressful and takes away a lot of time I could have to have fun or just relax. It's not easy but it is do-able if you have good time management skills. It's really a bummer at the moment.
