We have somewhere to rest our weary heads in Sydney on the way out and London when we arrive after 13 hrs of flying time - plus 3 hours before departure and 1 hour after landing - hopefully on time (fingers and anything else that helps crossed).
Using the "If it ain't broke, don't fix it" rule, we will be staying at the same hotels we have used over several years.
The Airport Sydney International and The Comfort Hotel Heathrow - nothing flash, convenient and good value.
It's better to travel than arrive ... then again ...
