I agree - with a caveat. Talk with your wife about it.
Many times people have fantasies that really, really get them off to think about, but actually doing it is something they don't really want. If this is the case with your wife, making arrangements without discussing it with her could end in hurt feelings all around.
On the other hand, discussing your desires with her and your hopes for some fun - discussing it OUTSIDE a sexually-charged situation - could be the next step to realising those fantasies. Who knows, she may want to be involved in making arrangements ahead of time, or she may enjoy it if you arrange a "chance" encounter without informing her of the details. But please do talk about it.
Have fun and use protection!
