When is it too late to add trip insurance?

[Pezalicious]

Long story short, my grandma is in the hospital and we were told that they don't think she'll make it home. Our Disney trip starts 2 weeks from tomorrow.. is it too late to buy trip insurance?

Q.

What is the latest date I can purchase travel insurance?
A.

You can purchase a policy up until the day before you travel. Some policies are available for purchase on the day of departure, however, our recommendation is to purchase as soon as possible to maximize your benefits. If you wait to make a purchase, you run the risk that something will happen before the policy takes effect.
