We are going to be there May 21-28. To be completely honest, I'm very frustrated with planning this trip. This is our family's first trip to WDW as a whole (well, my parents have visited 25 years ago but lots have changed since then). I planned very carefully to make it a magical experience for each member of the family, but Disney did throw some curveballs.
They announced the end of Star Wars weekend, delays in ROL and FEA, and possibly the most frustrating change was announcing MK Magic Morning on my MK day. If I had known, then I would probably have selected a regular EMH day since we're staying on site. I for one, do think my vacation is worth a little less now because if we were to attend just two months later in late July, we would (most likely) be seeing ROL, FEA, and the new Soarin while BTMR would still be open.
Will my family and I have a great time? YES. Am I grateful for the opportunity to finally visit WDW? Extremely. But I am disappointed in all the changes that are constantly being made after I had to commit to certain dates and park days (ADRs, FP+).
