<p>THIMUN is much different than ISLP. THIMUN is much shorter. So of course it is less expensive. It also takes place in only one city. ISLP typically goes to at least three cities. And THIMUN is a model United Nations. So it is more appropriate for students that are interested in the UN. ISLP has programs in business, diplomacy, medicine, engineering and archaeology. I just don’t see any comparison…</p>
