At RPR, there is a smoking area just at the very bottom of Tower 3. When you exit the elevators instead of heading straight towards the pool/water taxi doc, you turn left. Not sure where else at RPR but perhaps there is one at the base of towers 1 and 2 as well (never checked as we were in Tower 3 last time).
As for the parks, smoking areas are numerous. Way more than Disney (Magic Kingdom only has 3 in total).
Off the top of my head in IOA, there's one in Marvel land on the right along the water. In Toon lagoon near the bridge between Popeye's and Dudley Doo Right. In Jurassic Park in a tucked away passage near Raptor Encounter and I believe one across from the Discover Center. In Lost Continent on the left just before entering Hogsmeade. Also one along the lake in the Port of Entry area.
In UO, there's one in the square across from the Mummy. One in World Expo to the right of MIB. In San Fransico behind Richter's Burgers (around the corner from the big Jaws hanging there). One just outside of Springfield in the wooded area (near the Delorean from Back to the Future).... Umm there's more. Just can't remember.
There's lots though and your Husband won't be too far from one where ever he is in the parks.
