The earliest check in I saw on these boards is yours: 4-19 ! I believe a few people are checking in on that same date, and that is the earliest anyone has reported getting a letter with any kind of gift card promise (or any other credits).
We are checking in that following weekend, and I have received that same email; that all the restaurants and shopping will be closed, and that we will receive the 75 dollar gift card. We had never received a 25 dollar gift card email.
Interestingly, just two days prior to receiving the email, I spoke to a cast member, who verified with another manager, and told me, that there would be no tents, no noise, no closures, and no prep work whatsoever before May 1st.
I was assured, that the gift shop and food court would be fully stocked, business as usual. The follow up email then said flat out that everything will be closed, and it has our reservation number and dates on it. I plan to print out and bring the email. At this point, I do not know, what to expect, and it is too close to our travel date to make changes. I am hoping for the best (no or minimal disruptions) and will be thankful to people reporting here on the status of the resort...
