Learn English – How make salutation to multiple recipients `Dear Sussane, David & Joshua`? (and other queries)

grammar

For an exam answer, I was required to write a letter to invite my friends to my city. I have some specific queries about it, but I've put the whole thing for some context. The problem phrases are in bold.

Dear Sussane, David & Joshua

I am excited to receive you all on Sunday next week at Hyderabad Airport Central.
Therefore, there isn't any need to worry about logistics from airport to my home.

Let me share the vacation plan that you would think of spending here. This city
has an history of Nizam Royal Family, whose heritage is left behind 400 years
ago. Some of the obvious destinations that has to be visited are Charminar, Golconda
Fort, Falaknuma Palace & Ramoji Film City.

Hyderabad hosts a Zoological park. Therefore, You could think of coming with
children for this trip. Children can have some learning experience at Salarjung museum. > For a comfortable trip this would not consume more than 4 days.
Therefore, Please plan accordingly and make me informed before starting from
there.

Yours lovely,

Rebecca

My question:

1) Can i address the recipients with multiple names, when i write a letter? by saying Dear A, B & C

2) Could i use a better phrase than saying left behind?

3) Can the heritage destinations be mentioned with Initial Capitalise letter? for example: Charminar Zoological

4) Can i better the wind-up statement at the end of the letter? Looks like I did not phrase it concisely before starting from there.

Best Answer

(1) You can definitely address more than one person in the salutation. I would personally write out "and" and not use an ampersand.

(2) ...whose lineage dates back 400 years.

(3) If zoological park is part of the name, it's capitalized: The Miami Metro Zoo.

(4) I don't understand what you mean by "before starting from there."
