Three months out
Flights, transfers and experiences fall into place. This is still comfortable for most places, but choice narrows for the most sought-after properties.
Less than a month
It is still possible, and we have done it, but you will be choosing from what is left. If your date is close, speak to us early and we will tell you honestly what is realistic.
