Help! I've been planning a trip to WDW for next month since March. At the last minute my sister decides she wants to go. She has no job, no money (except a credit card that she is anticipating anyday now with a $200 limit). To top it off, she's bringing her soon to be 10-month old with us. Now, I have a room reserved at Pop Century for me and my two friends (one who's never been to WDW). It's already going to be an extra $10 per day for that extra adult and with my sister coming, that will be an extra $30 that she doesn't have (nor what I want to spend). My friends and I were planning to hit all four parks with MYW hopper tickets totalling $164 each (I have an AP). How do I explain to my sister (without getting her angry) that she can't go? It's not like she has extra money in the bank and she plans to max out that new credit card - which is a bad idea in itself. She cannot possibly afford to buy tickets for the days we'll be park hopping, pay $30 for her share of the room, and have money for food. It will also be hot in July and a baby will put a halt to our mobility. She also has a history of bailing out on paying her share of expenses when we go anywhere requiring an overnight stay or paying for entrance to a park. I love my little neice and would love for her to be there, and if my sister had the money to go without causing me any extra expenses it would be no problem at all. I'm not a Scrooge, I just don't have the extra cash and I don't like to be used. What do I say?
