What a site! First trip with kids-food allergies

[Mum23]

I've been lurking for a while now and after much discussion we have booked our first trip, still several months away.

I am a bit freaked out for several reasons the biggest being traveling and providing food for my kiddos with multiple food allergies while at WDW.

I do have a question about the Wishes Cruise. I poked around and saw there seems to be a split on doing the Wishes or the Illuminations boat cruise. We have a 7,5 and 3 year old at the time of the trip along with grandparents. Which would you choose? Is it worth the added expense or would catching the fairy to the MK at the right time be just as good?

Thanks so much for all the info you have already provided!!
