JQuery UI DatePicker using 2 date fields trying to get date difference

Question

I have 2 JQuery Date fields

1. Arrival
2. Departure

Arrival date must not be todays date - i got this sorted using minDate: 1 in the javascr

Answer 1

I think the functionality of the arrival and departure shoud be reversed/swaped. I just changed over the labels and things became clearer but now the code looks wrong.
