Depends on traffic. I'd say allow about 45 minutes. Expedia shows 35 minutes, but you never know traffic.
However, I didn't realize the Bee would be at the Convention Ctr - I was thinking you had to be near Dresden. Since it's the CC, I'd suggest these at nearly the same drive time:
Cross Creek Camping Resort
Alum Creek State Park (across the street from Cross Creek)
Delaware State Park is another option, although we personally haven't stayed there
Cross Creek is, IMHO, a top-notch full h/u CG with nice sized lots (many with patio pads). I can e-mail you some photos if you want. Alum Creek SP has lots of large, well secluded sites & a huge beach area. I know Delaware SP was doing lots of upgrades last yr. But as with most OH state parks, there's just electric hookups, you have to port your water. CC & AC are both near a major interstate exit where there's a bunch of places to eat. Delaware is next to a major state route & just a short trip to eatteries.
As was with Lazy R, with traffic, you'd be about 45 min away from the CC from any of the additional GC's I listed.
