Upgrading to TS DP

[mummabear]

If I upgrade from the quick service DP on the FD promo to the next one up which I understand will cost me $600USD for 2 Adults and 2 children, do I pay that extra amount upfront or when I settle the rest of the package cost?

Settled with the rest of your package cost before the 45 day mark due date.
