Are you going to shule shavuos night primarily to schooze with friends, eat cheese cake and baked ziti or are you going primarily to be osek in talmud torah?
I am going (as I have many times in the past) because a) my Rov is giving the first shiur and his shiurim are always interesting and b) my son is giving the second shiur and …ditto. I am trying very hard to stay up all night and attend ALL the shiurim, so that whatever learning I am able to do will be in the zechus of a young relative of mine who is very ill and in need of a refuah shelaima and neis b’korov.
