I am just about to book my RTW ticket, I have opted for London - Bankok -overland to- singapore - melbourne -overland- Cairns - Auckland - LA - Dallas -San Francisco- vancouver.
The problem is that the world is my oyster and i still have one last stop to pick. The choices are;
Please help, I really can't decide which one to take, has anyone any suggestions or advice?
Obviously it's entirely up to you, but my thoughts are as follow:
From a variety point of view, I'd say Namibia or South Africa (i.e. fly in one, overland to the other then fly from there). That way, you will get to another continent, and completely different experience etc.
I'd save India for another trip when you have time to visit it properly for at least 2 or 3 months, instead of just 2 or 3 weeks which is what most people seem to do.
Ignore New York and Montreal. Both are relatively cheap to get to from the UK (in comparison to the other places you have listed) and you can get there for shorter breaks in the future.
If you really want to visit Perth, you could consider including it instead of Melbourne and then travel Perth - (Adelaide, Melbourne and East Coast) - Cairns overland.
Hawaii would be worth it if you fancied some proper Island time on a beach.
Depending on time and how the ticket works, you could probably also gain an extra leg by travelling overland between San F and Vancouver along the coast, which everybody says is an amazing journey, although will take time.
Don't know what time of year you will be in Oz, but the best time in Perth would be summer when you can sizzle on the beach, snorkel all day and party all night.
As you are already doing Melbin then overland to Cairns, that is one big stretch of Australia already.
Namibia and South Africa sounds pretty amazing.
