Adding someone to a booking

[shagster330]

We are looking for a bit of advice for adding someone to a booking. We have booked up for 2 adults and 2 children for AKL and offsite at the Wyndham resort for next February. My dad has agreed to come with us and we are looking at the best way to add him to a booking. We booked through Jetsave at First Choice.

He is going to have a separate room so I realise he will have to pay a supplement on this. Any tips on booking for a single traveller, and saving costs

Thanks
