Sorry to say that while there is a good chance that you will get the tickets, it is not 100% certain. Hopefully you have a good seller that will come through for you.
I am the same boat with a differnet event happening in Las Vegas, and I live in NY. Just chated with support and they stating my seller has a good rating for fullfiling tickets (not 100%), but I can not take the chance, so I bought additional tickets that can be instantly downloaded, and hoping to sell my original tickets, and if the seller doesn't fufill then Stubhub returns my money.
In the future be sure to click on the "Instant Download" option when looking at tickets, so only see tickets that you can be immediatly received, or just use the original ticket provider, if there are plenty of tickets available.
