advantages of roommate?

<p>Hi,
How are the single rooms compared to the doubles or triples? is the double basically double the size of the single room or not? Also, what are the advantages of having roommate or not having roommate specifically at dartmouth. (e.g. i heard that triples are located all the way at the river, ect).</p>

<p>Son had a single freshman year, at the river cluster. Most of his floor mates also had singles. They remain best friends years later.</p>
