Am I asking too much?

My boyfriend of 6 months and I haven't travelled together before and now we're going on a business trip to another state (both our dates collide). I was excited to learn our dates collided so I asked if we could extend our stay for another day just to explore the state, but he isn't interested.

The airfare is covered by our companies (we're just travelling on another day to what was previously assigned), the extra day for accomodation will be covered by us.
