Sister Trip

So I was talking to Felicia about a friend I have and how they do a "sisters trip" every year. So I was thinking that we should do that. Maybe not every year, but every other year, what do you think? What they do is rotate through where a "sister" lives and do something for a long weekend.  They usually do it at Christmas time, but Felicia and I were thinking that an off time of the year would be better for 2 reason, airfare would be cheaper and husbands wouldn't have to take time off from work to watch kids. Talk it up.
