You have clicked this title because you want to know more about how to write holiday greetings. Thats very understandable, because there are very much different ways how to write about the common holiday greetings. I could give you a list of examples, but that would be , how to say, copy and paste , and thats probably not how you want to write to your home front your holiday greetings.
Be precise and to the point how to do it. First you take a notebook with you on your holiday. Write down basic terms, about the scenery you see, the clubs you visit, the vehicles you have used, the beach you have visited. Next to them you write down your experience you felt when using these in your vacation. When you have finished that, then now you are ready to write your holiday greetings to your home front. You can now create a story in which you are the main person who is experiencing the holiday, and that you think of your [home front] and you then can use the terms and experiences you have written down on your holiday, so you will have a good glossy story which is fun to read for your audience.
It’s very important to tell in one of those experiences that you thought to write home, and after a few other events (that is usually the truth 
) you began writing the story to read for your reader(s) . After that, just continue with events you already experienced, and the ones you still want to experience.
Look at the story you write as if the one reading your story would experience the holiday himself just in an imaginary way. Share the feeling as if the reader could feel what it is to sit beneath palm trees, or swim in the sea with water of good temperature. Or if you played with the children on the beach in a game of beach volleyball. Give advice what clubs to visit if you had a nice experience in those rooms.
Tell them what you saw when you was taking that tour with the bus, train , or renting that scooter, or enjoyed nice music or opera. After your story is long enough and reads fine, mail it to your audience. Its That Simple. There are many people who do not know how to or where to begin if they want to write their holiday greetings.
The trick is to keep it a short story, and use the highlights of your holiday so your story would fit on a postcard. If the story doesn’t fit on a postcard after all because its becoming too long, continue to write on another piece of paper, and post the postcard along with the used paper with the complete written holiday greeting story on it, in a standard envelope. This will prevent to throw away valuable time you spent writing on your postcard only to find out there wasn’t enough space. Do not forget to buy enough postal stamps.
I hope you have a good holiday experience, and that my story is a good advice for you so you now are able to write your holiday greetings, the HELIUM style..
Friendly greetings.
