Just me personally I wouldn't discount Anegada even if all you have is one night. You're on a PC with a cruise speed somewhere around 8-10 knots. You are about 2 hours from the North Sound. Our last trip was

1 Norman
2 North Sound
3 North Sound (Rent a car and see the sights)
4 Anegada
6 Diamond Cay
7 Peter Island

We certainly were not rushed and had a great time. Just my two cents but you could wake up late in the NS and still be on a mooring in Anegada by noon and have the whole afternoon to take a romantic walk around the point at Cow Wreck.
