<p>I haven't visited Dartmouth yet, and I know you must be invited to Dimensions, but do they have any sort of other official day where you can visit? Thanks.</p>
<p>your post is a little confusing. if you are admitted you will be invited. if you can't make it those days, you can go any other day you want, it just won't be with 500 other admitted students. if you are ED, you can go to Dimensions anyway, you just have to find your own way there and your own place to stay. If you haven't applied yet, you wouldn't want to be there for Dimensions and you can go any time.</p>
