BF and I love doing the early morning CP breakfast! Since we will be there for 2 weeks, this time we also added LTT dinner, like you. When I was down in FL during my WDWCP, my roommates and I did a few character meals to celebrate and had a great time at all of them.
There are always a few adult only tables and I don't think you'll feel out of place. It is a fun part of a WDW vacation and I think most people with or without kids try to include at least one.
