I voted "other" because it's a combination of "rotating" and "same house".
DH and I don't host any holidays, because even at 30 years old, we're still considered the "kids". Easter breakfast is at my parents' and dinner is at my in-laws', then we go to my aunt's house for dessert. Thanksgiving dinner is at my in-laws', then dessert at another aunt on my side.
Christmas is when is gets confusing. We have Christmas Eve dinner at my parents' house every year, then go to DH's aunt's house for dessert and then we'll go to midnight mass with his family. Christmas Day dinner rotates between aunts on my side. We usually eat breakfast at home, go to his parents' to exchange gifts, go to my parents' to exchange gifts, then go to a random aunt's house for dinner.
Luckily (or not, depending on how you look at it) we all live within a few towns of each other.
Holidays leave us exhausted.
