ho to get to Shenzhen windows of the world from ambassador hotel?

we'll be staying at ambassador hotel in shenzhen and we plan to visit windows of the world on our own(without a tourguide). here are some questions we have..
1.) how do we get there?
2.) should we take the bus? or the train/MTR?
3.) do they accept the octopus card from HK as a payment for MTR?
4.) what is the nearest station? and how do we get to that station?
4.) if we ride a taxi, how much is the estimated fare?

thank you very much! :)
