Often its not about you not moving back, its about not having the space to move back at all ..
Prime lenses are always better in (I)mage (Q)uality than their zoom counterparts, but you have to know exatly what you are getting into. Zoom lenses make up for their slight inferiority in IQ bu their flexibility in image composition. For your needs, a zoom lens to be a much better fit. And especially some thing like the 18-200 a fit it and forget it lens that can do relatively - wideangle to near telephot without ever having to change lenses.
This is probably my next lens (when it becomes available) - my needs are similar to yours btw:
