This type of letter would be considered as a letter in which you would not have to remain professional letters at all times. Thus, you could use any vocabulary and grammar you prefer, however you must keep in time that you must write depending on the person you are speaking to.
Dear Aunt,
I wanted to thank you for inviting me to visit you. It was a very enjoyable weekend visiting and I had a wonderful time with you. I remember us going to your farm and feeding the animals as well as going to eat in restaurants. I had enjoyed this very much and I wanted to let you know how happy I was to be with you, it meant the world to me.
I hope we can see each other again soon and continue the bonding in which we have established, as it means a great deal to me.
Sincerely,
Your nephew
