Is it safe to book a hotel?

<p>I am going to make a college visit to UMN and I already went to their website and signed up on one of the dates that were available. I was wondering if it's okay to book a hotel now or should I wait until they send out confirmation e-mail, if they do that is...? Keep in mind that I signed up yesterday evening and it's been a day. Do they send out e-mails to confirm?</p>

<p>We haven’t received an email back from them yet. After we signed up, it just gave us a message that we will receive a more detail agenda closer to the date. We made our hotel and airline reservations already.</p>
