You can do this a couple of ways.
All accommodation deals are fully refundable within 7 days if we're unable to match your desired dates. So, you can just make the purchase and then follow up with our customer service team (firstname.lastname@example.org) to confirm availability and book it in...or we'll refund you if not.
Or, if you'd prefer, you can reach out to the team before purchase and they can confirm availability. Either way, no booking for an accommodation deal is confirmed until a purchase has been made and the provider has confirmed the date.
