If you have dogs, be sure that the pet sitter has been to your house (several times if possible) while you are home so that the dogs understand that the person is allowed to be in the house.
You will need to be sure any pets you have are cared for in a safe environment when you are away – you can take them with you if your holiday accommodation allows, board them at a kennel or with a family member, or get a pet-sitter to come to your home each day.
You may need travel insurance, particularly if you are booking travel far ahead of time. This may allow you to get refunds for your expenses if you have to cancel your trip unexpectedly.
Many airlines charge customers per bag, so packing light will save you money. In addition to limits to the number of bags, most airlines limit the weight of each bag and will charge fees for overweight bags.
Pack a first aid kit, snacks, and entertainment for the travel time. Car trips and air travel both involve long periods of potential boredom, so bring games or activities for the travelers, especially if you are traveling with children.
Make sure you know about the weather of your holiday spot so that you can dress appropriately while you are there. You may want to pack a few layers or some cooler items to allow for unusual weather.
Be sure to include or even pre-pack very important items, like any medications you will need. Search online for holiday checklists to ensure you have all the important things. There are helpful resources that guide you in packing for different circumstances.
Well in advance of your trip, start a list of what you will need to take with you. Keep the list handy and add to it anytime you think of something else. What will you use every day that you will absolutely need while you are away, including identification?
The further in advance you plan your trip, the more time you will have to save for it. For expensive or special trips, consider asking family and friends to chip in to your travel fund in place of gifts for holidays or birthdays.
Know how much you will need for each aspect of the trip – transportation, housing, food, tips, activities, and all associated fees – and then plan extra for unexpected expenses.
