Hi ShuYan,
How are you??
We hope you are well.
The day you come to our place is approaching. Are you getting ready for your holiday?? We can't wait it!!
The reason why we are writing to you is that there is something we would like to ask a favor of you. Could you let us know your arrival time at our place?? Because it will be a busy day for us. Because we have some guest on that day other than you who will stay at our other studio. So we have to make a schedule in order to avoid a trouble.
Anyway we are waiting for your coming. And if you have any questions now, feel free to ask us. Thanks a lot.
Best Regards
Kentaro and Kyoko
