Bellvue is definitely a fun little course in Delaware - depending on what time you hit the area, and what your priorities are, I'd probably skip Bellevue, & hit Brandywine & Iron Hill. Brandywine is very scenic, not extremely long, and if its not super-windy, shouldn't take all that long.
Iron Hill is the gem (IMHO) of the state - long, wooded and multiple tee's/baskets to make it as hard or "easier" as you'd like.
Brandywine - I'd leave 2 hrs to play - can be tough to navigate if you're not familiar with it. Iron Hill = 2.5 - 3 hrs, as it's well marked, but loooonnngg.
If you have an entire day, or have no timeframe to really stick to, I'd throw Bellevue in as well, as it is fun to play, but out of the 3 courses very close to I95, it's last on the list as far as "must play".
If you want to camp as well - hit up Lum's Pond (camping & DG), and play White Clay as well! You could probably plan to play Bellevue & Brandywine, camp @ Lums that evening & then play Lums, White Clay & Iron Hill the following day & get back on the 95.
