If it were me (and I've been in the same boat as you more than once), I'd replace "every few days" with "at least once a day". You'd be surprised at how often things open up and are snatched up quickly by obsessives like me :-).
Good luck! As mentioned earlier, I think you're in pretty decent shape even with the seats you've got (barring an equipment change, of course)
