If you are both strong riders and have a lot of miles in you will be o.k.
Communication between you two and other riders is key.
If there are hills or head wind you will suffer. You can't move around on the bike as much and for us 60-70 miles is a long ride and a century is another step up, perhaps bordering on not so fun.

I'd definitely agree. Something about the tandem, perhaps because you tend to not move around as much, makes it more tiring to do long rides than on a single bike. And if you're brand new to tandems the problem will be worse (for example if you're not comfortable standing to pedal on climbs, or just for a butt break).
I'd consider doing the Metric option if they have one.
