Sounds like the nap-dropping is happening, like it or not, but it's a longer phase for some than for others.
What we did was to institute "quiet time" after lunch: I'd put on an hour-long-ish CD and DD could play in her room while I got my ME time. If she napped, I'd cap it at an hour or so, and if she didn't she got an early bedtime (and yeah, afternoons sucked, but she'd at least had some downtime even if she hadn't napped, which helped).
Given the choice, I'd go for the option which gives me an evening w/my partner and a tall glass (or three!) of wine. LOL
