Eloise at Christmas is a charming story. Eloise lives in the Plaza Hotel and during Christmas, there are all sorts of fun and chaos. She gets involved in decorating, meets interesting people, and generally spreads her unique brand of mischief and holiday cheer. For example, she might try to help the hotel staff with the Christmas tree but ends up making a bit of a mess in her own Eloise - like way.
In a Christmas story taking place in Plaza House Square, the square could be transformed into a winter wonderland. There might be ice skating rinks set up, and people of all ages are having a great time. The local church might organize a special Christmas mass in the square, with the beautiful sound of bells ringing in the background, and everyone coming together to celebrate the joy of Christmas.
In the Eloise Christmas Story, the main events start with the arrival of Christmas - themed items at the hotel. Eloise gets excited and wants to be in on all the action. There are preparations for big feasts, and Eloise might try to sample the food early. Then there's the waiting for Santa Claus. She may leave him a special note at the hotel's grand fireplace. And of course, there are the Christmas carols that she might sing along with or cause a bit of a ruckus during.
In the Christmas story set in Plaza House Square, there could be a young couple who meet there for the first time during a Christmas fair. They fall in love while sharing a cup of hot chocolate and looking at the beautiful Christmas displays. As the years go by, they get married and every Christmas, they return to the square with their children to relive that special moment. The square becomes a symbol of their love and the start of their family's Christmas traditions.
I'm not sure specifically which 'eloise novel' you are referring to. There could be various novels with this name. It might be about a character named Eloise and her adventures, relationships, or personal growth.
