I've run 11-28 on 7 speed before. It's an arse if you're trying to keep up with people as the jumps between sprockets are quite large - try to get a 13-28 if that exists in 7 spd, If you're just touring, you'll likely never use the 11 or even 12.
^^ I think I'd rather have a compact double with a long cage mech / 32 sprocket than a triple. I am a bit of a tart about these things though.
