Thank you! Yes it was customised. We contacted them via email and discussed what we wanted and what was reasonably achievable. They then emailed us a suggested itinerary and a quote.
They were very flexible. Even on the day, we were advised that we could chop and change if we wanted. We ended up having lunch earlier, stopping at a playground for ice-cream, stopping for an unexpected shoe shopping expedition for our youngest, looking up lost family and still saw what we wanted see!
