I'm also sure the answer is no. EMH are for WDW resort guests. As a VB guest, you're not a WDW guest and I assume would be similar to any other off-site resort.
When you check-in at VB you might ask to see if they know or not.
If you go over to WDW, for EMH, before they give you the band, they scan your room key card. So the card probably has codes that state the resort you're at and the dates of stay.
The CM's giving out the wrist bands probably don't know themselves if you're eligible. You might just explain to them you're staying at Vero Beach and didn't know if you're eligible EMH or not, and just have them scan your room card and see what happens. The computer will either accept it or it won't.
Also, don't forget, for EMH everyone must have their own room key card to get a wrist band, so just in case it does work, make sure everyone brought their cards.
That's why at WDW resorts, everyone in the room gets a card, including the children.
