Make up an English conversation with the room service staff to guide the guests into the room.

I can see that what you need is a daily conversation about hotel English. The following is a passage I wrote, which is estimated to be able to cope with any foreigner's visit:

The foreigner's name is John, instead of J, and the waitress's name is Miss instead of M:

Hello, sir, please follow me. This way, please (this is your guide for foreigners).

When we get to the room, you will say:

m； How was your trip?

Yes, it's good. The service of the plane is good and the seats are comfortable, but I'm a little tired now.

Oh, maybe you should take a bath, which will make you feel better. Now I'm going to set the shower time, and it will be ready in a minute.

j； Oh, great, thank you very much.

M: This is our job. Please feel free to call me if you need anything.

j； Thank you for everything. I promise to call you if I have any questions. Thank you again!

Ok, I have to go now. See you if you need anything! see you again

J: goodbye

I think it should be enough. Too much is a burden. Suitability is the best. Foreigners feel comfortable but not disgusted!
