Is this a good letter/note?

Question

Its for these kids that I worked with in the store where I work this summer that are leaving soon.

(Name) and (Name),

I'm glad that I got to know you both this summer. And I'm sorry I won't be able to see you on your last day. I hope you had a good time this summer and I wish you all the best.

Sincerely,

(my name)

Answer 1

~~Yes only two suggestions. Write each note to each individual. The first sentence should say I am so happy  I got to know you. The rest of it is great. Individualizing it makes it more personal.~~

Answer 2

Try-- "I wish you all the best!"

You don't want to keep in contact?  Or just offer your email?  That seems a little more personable, even if you don't expect to keep in touch.  I think it's a very sweet note :)

Answer 3

I think that's a great note! :)

Answer 4

Yes. It's sincere and let you say good bye on a high note.  

Answer 5

Yes, it's sweet and sincere. Take out the "And" before I'm sorry though.
