If you're going to be traveling routinely, it's worth buying duplicates of key items and leaving them in your travel bag, versus remembering to repack them after using them at home. For me, this is things like laptop and phone chargers, toothbrushes, and basic toiletries. I rarely forget these necessities since I have a travel set that's always in my suitcase or laptop bag.
The one thing I really have to disagree on though, and think you’re mad for not doing, is collecting points and airmiles. I cottoned on to this a few years back and every single trip I’ve taken since then has been by using airmiles and reward flights. I’ve travelled to Thailand, Finland, Croatia, Italy, Spain, South Africa, Germany, Norway and more – all with points and just paying the taxes in cash. It saves a tonne of money and even if you use budget airlines most of the time, if you pay with a points-earning credit card then you can still collect points to use on airlines where you may want a better quality experience, for a longer flight for example. I would seriously recommend American Express – I’ve had the Amex Gold, BA Basic and BA Premium Plus cards. I’ve also just applied for the Lloyds Avios rewards visa and mastercard combo for when we spend a year abroad, which also comes with 0 fees on foreign spend and earns you points. If you want more info, I find this really useful:
Wearing a money belt or neck wallet lets you keep your valuables close to your body and away from prying hands. Review all the different styles here to choose what works best for you and the type of travel you’ll be doing. You may also want to choose an option with RFID protection. RFID protection keeps all passports with an RFID chip (issued after 2006) and credit cards/debit cards safe while travelling. How? It’s simple. Identity theft can occur when someone is able to “read” through your purse or pocket via the microchip, which has personal information stored on it. By using an RFID blocking technology, your personal information is protected. You can learn more about RFID safety from Scott Shelter, freelance journalist and frequent traveler.
If you're traveling to a "regular" city and you're not taking clients out, a great way to save money is to get a gift card to a chain restaurant(s) you like. You save time, as you know the menu in advance and you potentially save money/hassles over unknown local options/hotel offerings. Of course, make sure that the chain exists where you're staying and this advice is for "regular" meals only - not trying local cuisine. This way, you can focus on business with one less distraction.
Whether it’s that steamy romance novel, thrilling sci-fi, or a dog-eared travel guide, download it before your trip. Even if at home you’re a paper-til-I-die sort, save the space and weight for your holiday. And don’t count on wi-fi to jump back into the story from your perfectly positioned beach chair. Make sure it’s on a water-resistent covered device (check out Otterbox for some serious protection for your cherished e-reader, phone or tablet).
