Anniversary Trip??

First of all, I can't believe it's even almost time to think about our anniversary, but it's quickly approaching! We have been wanting to plan a small, inexpensive trip for our anniversary and while we have a couple of ideas, I would appreciate any input you have. This will be just a Thu/Fri-Sun trip and we will have about $300. These are the things we've considered:
1. Beach trip. We have a friend with a house at Holden Beach. We could stay there most likely, relax and have a nice dinner Saturday night.
2. Camping. Less money for lodging = more money for something like whitewater rafting or going to see Biltmore.
3. Carowinds/Busch Gardens for the day, stay somewhere inexpensive that night.

More ideas? Let me know!

Coming later this week: my new recipe book and why it makes me so happy :)
