Which one is more cost-effective, Macau travel or Taiwan travel?

It mainly depends on whether you have any special yearnings.

I have been to Macau several times. It is very small and can be visited in two days. Basically, they all have to be in gambling towns, so you can go and experience them, and if you are lucky, you can also go and gamble a little. For transportation in Macau, you usually take the free bus from the casino. There are free buses to the casino at the port, the airport or the Hong Kong-Macau Terminal. Those attractions are almost near the casino, so transportation fees are basically free. It's more expensive to live there, with a minimum of seven hundred or eight hundred and one nights to get a similar stay. When it comes to eating, it’s up to people to be thrifty.

I have never been to Taiwan. . .
