Tomorrow we will be using my House Seats account to go to the sixty-fifth event in a little over a year!
There is no doubt in my mind that HS is absolutely worth it, so much so that I have already paid for a membership through 2015. I would give tips to better secure your chances to reserving tickets to the most highly-sought after shows that are quickly snapped up but I really would not like something like that easily searchable online (message me if you're a friend). I would also detail exactly what shows we have been to with our respective accounts but that is strictly prohibited by the TOS to ensure shows/tours/events do not suffer from lower public perception from the mass public.
One thing I will say that another seatfiller competitor does better is that they permit members to cancel reservations when you do it at least several hours in advance. - E
