Hi all

I know you can select your seat on VS's website if you make a booking with VH. My question is at what stage can you do this? As soon as you have made the booking? Or does the whole holiday have to be paid off and tickets issued before you can access the seat map? I'm thinking of booking to Grenada for Jan 2010 and i'd like to know if I can pick my seat at the time of booking, or only at OLCI. Thanks guys!
