It really depends on your nephew. My cousin was having a hard time for a girl to lose his virginity so I made a special arrangement to see a really cute SP. Since then, I am his favorite cousin!
I hate the short session since I feel very rushed. The shortest session for me is one hour while the longest one was 4 day long! I took my favorite sp to Mexico and had an awesome time.
So I got the tickets through the stubhub and had pretty good experience even though I had to pay 50% more than face value. Since Canucks are playing well, it's getting hard to get good tickets.
