I know my DW is going to feel guilty going to the parks without her sister. I am just going to have to keep reminding her that the trip is for us and our son. Not for her sister and fiance.
I usually don't contribute to these sorts of threads because they bring up too many painful memories of vacations that were derailed by one particularly insensitive and oblivious family member... but here goes.
I assume your SIL and her fiance are both adults, capable of making their own decisions. SIL has stated that saving for her wedding is more important to her than going to the parks while at WDW. (Personally I think there is a middle ground somewhere where she and her fiance could buy the cheapest possible ticket and enjoy a few park days, but it's her call.) You planned this trip for your wife, son and your son's grandparents and you simply must go ahead and do everything you have planned. Don't let anything or anybody spoil this very special time for your (immediate) family. Just keep reminding your DW that this trip is for your son and a thank you gift to MIL and FIL. No matter how close DW is to her sister, I cannot imagine she would choose to shortchange your son and her parents in favor of her sister, but she may need to be reminded of this periodically since she is prone to feeling guilty. If she starts to falter and shows signs of staying behind one day to keep SIL company, just say "What a shame you're going to miss seeing our son take his first ride on Dumbo." That ought to bring her back to her senses!
If SIL and fiance want to join you either at the parks or for dinner, they need to pay their own way. If they choose to hang out at the pool rather than go to the parks, then let them do that and suggest a time to meet up later. I'm guessing after SIL realizes nobody is going to hand over the money for their tickets and fiance realizes they traveled all the way to WDW just to sit by the pool every day, they will change their plans and decide to join you. If they don't, it's their decision and you need to remind your DW that she has no reason to feel guilty about that, especially given that fiance has sufficient income to pay for the tickets. And besides, you're all going to be living together for several days, so it might end up being a good idea to have some time apart anyway.
As far as having dinner together goes, if it hasn't already been made clear that they are responsible for paying for their own meals, here's what I would do -- as everyone is looking over the menu and before anyone orders, turn to them and casually say something like "I don't know if they will do separate checks here. How do you want to divide up the dinner expenses?" I would hope that fiance is a decent guy and in addition to paying for his and SIL's meals, he will want to treat you and DW once or twice during the trip to thank you for the free lodging, but at the very least, make sure it's clear there is no free lunch (or breakfast or dinner) here. If you think there is a possibility that SIL and fiance don't know what they are getting into financially when it comes to Disney dining, print out menus from
www.allearsnet.com for all the restaurants you will be going to and give them to SIL in advance of the trip. That way, SIL and fiance can decide if any of these places are out of reach and they would prefer to do their own thing on those nights. Otherwise, you might find SIL complaining at the dinner table "Look at these prices! How will I ever be able to pay for my wedding when I'm spending so much money on dinner!"
Bottom line, it's YOUR vacation. SIL has already caused enough disruption by changing her plans at the last minute and bringing along another guest that you never even invited! Remind your DW as often as necessary to keep the focus on your son and his grandparents and carry on with the plans exactly as you made them. Let SIL and fiance decide when (and whether) to join in, but don't let that affect anything you plan to do.
Good luck!!
