Which stop do I have to take .................?

Hi everyone,
Does any native speaker kindly help me with the correction of the following sentences?

1.Could you tell me which stop do I have to take for Enward Hospital?

2.I need to go Enward Hospital, could you tell me which stop should get off,please?

3.Could you tell me where is the nesrest stop of Enward Hospital, please?

4.Does this bus go passed(or past) Central Park?

I am eager to learn how native speakers convey these idea.
Amendment, guidance and suggestion would be greatly appreciation!

Seems you've got the right idea on all accounts.

Before getting on the bus, ask the bus driver (not a patron waiting at the bus stop, as they may give you incorrect information) #4: "Does this bus go past Central Park?"

After you get on the bus, you can ask the bus driver to alert you when your stop has been reached. Use: "I need to go to Enward Hospital. Could you tell me *when we reach the right stop*, please?"

Or, if you just want to know what the name of the stop you need to take is, ask #1: "Could you tell me which stop I have to take to get to Enward Hospital?" or #3: "Could you tell me *what* is the nearest stop *to* Enward Hospital, please?" or #2: "I need to go to Enward Hospital. Could you tell me which stop to get off at, please?"

Hi guest,
You have been very helpful, and I greatly appreciate that, Thank you very much indeed!!!!!!!!!!!!!
