Cindy,
Have a GREAT time at Hilton Head! When we were there for Spring Break we went to the movies at the Mall and they have the BEST popcorn. When you order your popcorn they just hand it to you and don't ask about butter. The reason is if you go to the left of the cash register there is a popcorn condiment bar. You can add butter or different toppings like white cheddar, jalapeno, ranch, etc. etc. We would go there again just for the popcorn!
Across from the resort in the shopping area there is a store that sells pirate t-shirts, etc. DH and I purchased t-shirts and I bought a banner for our door on the ship. I have worn my shirt a couple of times and have gotten a few comments! Too fun!
