Caitlet/ those who like Hilton Head

I go there every year for xmas or t-giving (my husband's whole family lives there).  Just curious, what do you do there/ why do you like it?  Maybe it's tainted for me because it's my inlaws!  In any case, we're thinking of doing our trip this summer because I won't want to travel in Nov.  So maybe in July it's a better place!
