First off, thank you to everyone on these boards. I have been reading them for months while planning my vegas trip. We are leaving next Tuesday and just received an email from Mandalay telling us (me, hus, kids 7&9) that we have been upgraded to the Four Seasons. I have no idea why this happened and I don't know anything about this hotel. I know it's the top floors of MB. Any insider advice? Will I be tipping constantly? Is it kid friendly? Do the rooms have two queen beds?Thanks in advance for any advice you guys can provide. I am such a planner and this has thrown me a bit but it's exciting too.
