I forgot to include these statements about a letter of inquiry to a hotel.

Which connectors shall I use to include my queries to the hotel?
Thank you.

4) I'd like to know the following things: First, if the bus line in front of the hotel goes directly to the city centre; second, if there are othe children aged between six and ten with whom my child can play ball games outside the hotel; third, if your hotel organises swimming courses for children; finally, if your hotel organises trips to the main attractions. I'd be grateful to you if you could e-mail me the list of the trips organized by your hotel as well as the week's entertainment program you have planned for the children (??)

spelling: other

Delete "aged" -- also delete "the" just before "children" at the end.

To include your queries to the hotel in a letter of inquiry, you can use the following connectors:

1) First: Use "first" to introduce your first query about the bus line going directly to the city centre.
Example:
"I'd like to know the following things: First, if the bus line in front of the hotel goes directly to the city centre."

2) Second: Use "second" to introduce your second query about children to play ball games with.
Example:
"Second, if there are other children aged between six and ten with whom my child can play ball games outside the hotel."

3) Third: Use "third" to introduce your third query about swimming courses for children.
Example:
"Third, if your hotel organizes swimming courses for children."

4) Finally: Use "finally" to introduce your final query about trips to the main attractions.
Example:
"Finally, if your hotel organizes trips to the main attractions."

Additionally, you can include a sentence at the end expressing your gratitude and requesting specific information to be emailed to you.
Example:
"I'd be grateful to you if you could e-mail me the list of the trips organized by your hotel as well as the week's entertainment program you have planned for the children."

By using these connectors, you can clearly outline your queries to the hotel in a structured manner.
