National Merit Finalists rejected from University of Florida?

My D got accepted into UF for class of 2024 with full ride being an OOS and a NMF. She got into their honors program as well. I contacted the financial aid office and inquired if it will truly be a full ride and they said they can only give you the award letter once you accept them as your #1 choice by 5/1/20. They don’t want to offer you the full ride and for you to decline the admission offer as it will create a mess involving the Benacquisto program. BTW, we signed up for the Florida Days in April because my D seriously wanted to consider the full ride offer from a great school but now that’s on hold. She said she cannot got to a university she has not visited so we shall see what happens.
