I want to book 2 nights at Vero and then go to OKW, my question is when I call at the 7 month mark can I book both resorts or do I have to wait the 2 days and call back and book OKW.
You are making two reservations, with different booking windows, so you will have to make two calls. Alternatively, you could wait until the OKW window opens and make both reservations on that day.
