So, my wife and I are kicking around the idea of planning a family vacation with my parents, my sister, her husband and their kid (who will be 16 next year). Much earlier this year I had looked at rates in Vegas for the week of 12/15 and the rooms looked way low, but I don't remember what the cost of plane tickets were. I looked for this year and they are something like $400 round trip per person from Sea-Tac, but considering when I flew in September my ticket was only $250, I'm assuming that the rates are inflated because their are so few seats left now. Are flights usually higher or lower around mid-December? Also, does anyone know if they tend to have any extra deals on tickets to shows around this time? Again, just wondering based on the rates that I saw for rooms.
