We are going to invite foreign engineers for a workshop in Japan. I would like to ask them whether they prefer to have dinner with us or by themselves.
We will have two opportunities at different places for dinner and are going to ask their opinion by e-mail.
Would you give me advice on the following message? We would like to tell them both are okay politely.
"We can arrange small parties with us at both Tokyo and Osaka. It is also okay for you to have dinner by yourself where you like. Would you please tell me your preferred option?"
Thank you.
