I've been on several budget road trips, and there are definitely ways you can keep costs down. For gas, apps like GasBuddy are a lifesaver. They let you compare fuel prices at nearby stations to ensure you're getting the best deal. Planning your route to hit cheaper gas spots can save a lot over a long trip.
For food, consider packing a cooler with snacks and meals you can easily prepare on the go, like sandwiches or salads. Not only does this save money, but it also means you'll eat healthier than fast food options. When you do want to eat out, apps like Yelp can help you find budget-friendly local eateries that you might otherwise miss.
As for lodging, booking sites like Booking.com and apps like Airbnb can offer discounts, especially if you're flexible with your dates and willing to stay a bit outside the main tourist areas. Don't forget about camping if you're open to it; many state and national parks offer inexpensive or even free grounds.
If you're looking for deals, Groupon can sometimes have discounts on activities in your destination cities. Lastly, make sure your car is in good condition before the trip to avoid unexpected repair costs.
Have you considered joining any loyalty programs for accommodations or gas stations? They can offer useful discounts and rewards, especially if you travel often.
