Layover in Hong Kong [closed]

I need a cheap place to stay. and How do I get to Central don't go well together. Central being the most expensive area in Hong Kong.

To answer the question about transportation, the most convenient and fastest is the Airport Express: there's a train from the airport to Hong Kong station (in Central) every 12 minutes, and it takes 24 minutes.

This train has a couple of stops on the way, which could be possibilities to find cheaper accommodation than in Central. Of course "cheap" is a relative term. Depending on your budget, there could be places on the Island that could be suitable for you.

Going back to the airport the next day, you can check-in downtown at the Airport Express train station, before taking the train to the airport. This is quite convenient, as you won't have to carry your luggage to the airport.

As for the visa, US citizens do not need a visa for Hong Kong and Macau.

Hong Kong and "cheap" don't go together well.

Hotel in the airport will run you at least US$200 / night but it's convenient and you don't have to pay for transportation. Close to the airport are a bunch of fairly affordable AirBnBs but availability is hit or miss and you probably will need a taxi to get there.

Kowloon may be a good compromise. You should be able to get a workable room for a US$100 or so.

Not sure how often you get to Hong Kong: it's a great place to visit and walking along the Avenue of the Stars or taking the Star Ferry is almost free. You may spend a few extra dollars to get the experience.
