1) Thank you for replying to my request today. ... I would like to book a room with a double bed and a single bed at..... for person sharing which includes breakfast and dinner for ... nights.

I don't understand the underlined words. Were two sentences mistakenly run together here?

2) How we can reach ..... from Dublin as we will be travelling by train.
How far is the nearest train station from your hotel?

3) What time do you think we will be in.... if we leave Dublin around 9:00 in the morning?

4) Do you think it will be possible for my child to take riding lessons during our stay at your hotel?

Sure! I'd be happy to help you check these sentences. Here they are:

1) "Thank you for replying to my request today. I would like to book a room with a double bed and a single bed at [hotel name] for [number of] people sharing, which includes breakfast and dinner for [number of] nights."

2) "Prior to my booking, I would like to know how we can reach [destination] from Dublin as we will be traveling by train. How far is the nearest train station to your hotel?"

3) "What time do you think we will arrive in [destination] if we leave Dublin in the morning?"

4) "Do you think it will be possible for my child to take riding lessons during our stay at your hotel?"

Please note that I have filled in some of the missing information (e.g., [hotel name], [number of], [destination]) based on the context, so you should replace these placeholders with the actual details.
