Thank you all so much for the quick replies! I'm planning to do a 2 bedroom villa if they go so she can have her own separate quarters to rest and get away from the kids. The place I'm considering also has a full kitchen, so if there are still eating issues, we can accomodate those by buying our own supplies. I also found a direct 2 hour flight to Orlando so she won't have to deal with lay overs or waiting too long in crowded airports (or my children, since we're going on a different flight!) I talked to her about it yesterday, and she sounded pleased that we would want them to come. I think I'll plan it, making sure we have the ability to cancel if needed.
Thanks again for giving me your experiences. It is so helpful. I'm praying she will be well enough to enjoy getting away. It would definitely be a nice change of pace from daily treatments and sickness, and the weather in Nov. should be great in Orlando!
God bless,
Laura
