This period is really the time to spend with family and loved ones, especially for those whose work doesn't always give them enough time to spend with their people, but for those who are always free and live with their family, they might not treat this period much differently unless for the celebrations.
For those who will have the time and don't get occupied with family, I don't see anything wrong with them gambling that period as long as they can afford the time and it won't distract them from anything. These days, it doesn't take much to gamble; any free period can be used, maybe 30 minutes or an hour a day.
Yes, it depends on each person's situation. If we are busy people and don't have much time for family during the year. And holidays are the only time we have the chance to be with our family, we should put aside all work and personal interests to gather with our family. But if we work and live with our families, we can do whatever we want during the holidays, including gambling.
Like me, I work and live with my family so whenever the holidays come, we consider it a time to relax and have fun. Besides taking my kids out, I will spend time relaxing and gambling if I feel too bored in my free time.
