So I'm looking at possibly doing a RTW this April. I have a few questions and would appreciate FTer input. Right now I have not decided on which alliance to go with, but probably leaning towards Star Alliance.

1. I have never visited Asia (outside of India). I am looking at Japan for a few days and either Singapore or Hong Kong for 3 or 4 days. Of the two, which is likely to be a more enjoyable experience for a middle aged male traveling alone? I know that is a very open ended question. Generally speaking, I will plan on using public transportation for all in-city travel.

2. Hotels in Asia: Although the concept of the capsule hotel is very interesting to me, I don't think I would actually want to sleep in one. What is the Asian equivalent to Mercure / Ibis hotels? I don't need or want lots of space or personal attention. All I need is a comfy bed, bathroom with shower and some quiet.

3. Although the price difference is not as extreme as I thought to upgrade to Business class, is it worth it for westbound travel? I'm not really planning to sleep on the plane, and only foresee three really long flight segments (Europe to the US east coast, US west coast to Japan and Asia to Europe). On the other hand, the club access at the airports, priority lines and extra miles earned are probably worth it. I guess I need some moral support in spending the extra roughly $4500 or so.

4. Start point is probably either MUC or CDG. Do any European countries generally offer better deals for start points on RTW trips?

5. I'm planning on one night in London just to stay at a Yotel. I know that this is weird (I like weird hotels). Has anyone stayed at one of these and had a horrible experience that would make it not worth the trip? I love the UK but due to the exchange rate, have a hard time justifying a longer stop.

6. What are the VISA requirements for Hong Kong for US citizens? Does that allow travel into mainland China and/or Macau, or does Hong Kong have its own requirements and limitations if I were to remain in Hong Kong proper?

Thanks for any input.
