Should I see Pearl Jam twice? Melbourne

Saw Pearl Jam in Melbourne AUS last night for the first time, I'm 25. People in front of me had travelled the country to go to every show and others around me asked if I was going to the second show on Monday.

I wasn't going to because it's special and might be a once in a lifetime experience, I don't want to ruin the magic. But now I don't know what I'd regret more, not going a second time, or going a second time and losing 300 bucks against my principle of not abusing special moments. Maybe this is a silly question but I'd love to hear from people who've gone to multiple shows or just one and why.

Edit: bought a GC ticket for tomorrow. Thanks guys, what a bloody idiot honestly, of course I should go.

Edit: lined up at 12:30 and got same spot as the overnight campers who travelled the world for every show. Between two people behind the barricade of front row. Cried my lil peepers out for Black. Everyone's saying its the best PJ show they went to and I'm glad I was there. Beaming, I am.
