hiwaygal is right. The biggest decision in disney's eyes is whether is is custom or intimate (not a wedding vs renewal), there are different venues available depending on custom or intimate. The WP is available for both types, but to have WP with an intimate is costs more than the other packages.
Mjkaferle5, as the others have stated, the answer is yes. My husband and I renewed our vows last October for our 20th wedding anniversary. We had an evening ceremony inside the Wedding Pavilion. It was lovely. (If you'd care to read about the planning of my vow renewal, click here).
No matter where you chose to renew your vows, I hope its wonderful.
