AITA for Not Taking My Nephews to Disney World?

aita for not taking my nephews to Disney World ever since my wife got pregnant all she's talked about is how much she wants to take our daughter to Disney World my wife has always said it was the best part of her childhood we're now 25 and have a three-year-old daughter this will be our first family vacation just the three of us and we're going in October yesterday at a birthday party my two nephews s and nine came up to me and asked if they could come to Disney World with us I was a bit surprised because I hadn't mentioned the trip in front of them I said something like I'm sorry I wish you could come but we bought the tickets a long time ago and you'd be away from your parents for too long they said okay and went away about 15 minutes later my brother and his girlfriend Tori approached me and said their sons wanted to come to Disney World with us I replied that I knew because they had just asked me a few minutes ago they said you told them no Tori said looking upset we can't afford to add two more people for a week's worth of tickets and food I explained my brother suggested that my wife would make back the money spend on their sons within a paycheck and that it wouldn't be a big deal to take the boys my family seems to think that because my wife isn't right now we're rich which isn't true they don't seem to understand the difference between a stable income and being wealthy I told them that it was too much money to ask us to spend on such short notice and regardless of the cost my wife had carefully planned this trip around things our daughter would enjoy I gave examples like our reservations at Cinderella's Royal table and the bibbity Bobby Boutique The Boys Wouldn't enjoy half of what we plan to do and might throw a tantrum until we left or were kicked out this Behavior has been reinforced because they know they'll get what they want if they act out they accuse me of being selfish and said I should want my nephews to have this experience they also suggested canceling the earliest stuff we had planned for our daughter and finding activities that all three kids could enjoy I reiterated that this trip was planned for our daughter and that maybe next time we could work something out but I wasn't willing to have my wife rearrange the entire trip a month out I thought that was the end of it but then Tori sent my wife a nasty text it was long but she basically said we were being greedy by excluding two impoverished children from a trip that could be once in a lifetime for them she even sent bible verses to support her argument Tori isn't religious but knows my wife is so this was purely a manipulation tactic my wife is very kind-hearted and tor's guilt trip hit its Mark she asked me if I wanted to drop some things from the trip to try and at them I told her no I love my nephews but I'm really tired of their parents feeling entitled to our money and life I think my family should be able to take one Vacation by ourselves without being called greedy aita here
