This summer my husband and our two kids are going to England and Scotland for a month. We will be renting a car for part of our trip and my husband will be doing all of the driving. I have some questions about it. 1. Which rental car agency do y'all recommend? 2. Does my husband need to get an international driver's license? I've seen differing advice online. 3. My younger son is 7 and rides in a backless booster at home (Texas). What are the rules where we're travelling regarding carseats? When travelling here and renting a car we use in inflatable booster called a Bubble Bum but I don't know if that will be enough in the UK. 4. Which driving navigation app do you recommend? We use Google Maps or Waze here but I was wondering if those are the best choice for this trip. 5. Is there anything else we need to know? Thanks for your help. We can't wait till our trip.
