I agree with Caskbill! More often than not, the self-parking lot is a much closer to the "Courtyard" entrance to most villas than the valet parking station at the main entrance!
While I'm usually very generous tipping the staff on vacation, I save money at Beach Club by fending for myself simply because I can usually get in and out much faster on my own two feet! (Broadwalk is a completely different story and I always use valet parking there.)
Best wishes,
