Thanks to those who have replied so far.

We are planning to leave for Miami at the end of August, and leave the USA towards the end of November. We are visiting family in Australia over December and January then wending our way home via NRT/HKG/SIN where we hope to get some beach time before returning to the UK.

Gardyloo; thanks for the welcome! You make a good point about the weather in Miami/Bermuda; we had considered it but we are planning on leaving the USA during November so as I understand it the risk is there throughout that time. We want to drive down the keys but other than that we are planning to spend some time in Georgia and South Carolina. We have lots of side trips planned from our destinations.

As to the Hawaii visit, we don't think we will ever go there if we don't go on this trip so thought we may as well take the opportunity IYSWIM. Your comments however are very useful.

We will have a look at starting the USA section from the west coast and see how that works (including the Chicago/Dallas flight info for the Hawaii leg) then make a final decision tomorrow.

I will hop over to the BA board and make a start on that!
