Enterprise AEs - how’s the travel?

Enterprise SaaS AEs (both large and small), how much do you travel? Is it mostly day trips or are you gone several nights in a row?

I’m thinking of pursuing a career in sales (currently a manager for a deal support team) but one thing that’s always concerned me was the travel. I like my routines and my wife and I are planning on having kids soon, doesn’t seem right to leave her and the kids home 3+ days a week.
