Never eat in a touristy area or near a tourist attraction
The closer you are to tourist attractions the more you are going to pay and the worse the food (and service). Use websites like Yelp, Google Maps, Foursquare, or Open Rice to find some delicious and popular restaurants around you.
Always visit the local tourism office
They know about everything going on in town. They can point you to free activities, special events happening during your stay, and everything in between. They even offer discounts on attractions and transportation. It is their job to help you experience the destination better. It’s amazing how many travelers skip this when they are visiting somewhere but, as a savvy traveler, you know to use this resource! This is probably one of the most underused travel tips in the world. Use the tourism board! Save money!
Take free walking tours (in Spain there are a lot)
Besides being free, these tours will give you a good orientation and background of the city you are visiting. You pass the time, you get to pepper the guide with questions, and you get to learn so much about where you are! Take a walking tour when you travel!
Get city attraction cards
If you are going to visit a lot of museums and other attractions in a short period of time, a city pass is going to save you money on admission (plus most provide free public transportation too!).
Be flexible, don’t overplan your trip
Let your days unfold naturally. Schedule two or three things and let the day fill in the rest on its own. It’s less stressful, and letting the day just take you is one of the best ways to travel.
In Spain there is “El menú del día”
Avoid Starbucks, McDonald’s, KFC, Burger King etc. In Spain there are hundreds of bar/restaurant to eat on a budget, they all have good quality-price food and during the weekdays all of them have menus for lunch from 7€ to 10€. This is a really amazing way to eat wherever you go ‘cause is in all Spain.
Be frugal — but not cheap
Don’t be pennywise but pound-foolish. Look for deals and don’t waste money, but don’t miss out on great experiences or walk 10 miles to save a couple of dollars. Time is money. Spend them both wisely.
Make extra copies of your passport and important documents
Don’t forget to e-mail a copy to yourself too. You never know when you might need to have some sort of documentation with you and might not want to carry your original. Additionally, if your passport gets lost, having a copy will come in handy for your police report.
Wake Up Early To Avoid Crowds
Rise before sunrise to have the best attractions all to yourself while avoiding large tourist crowds. It’s also a magical time for photos due to soft diffused light, and it’s usually easier to interact with locals getting ready for their day.
Keep An Open Mind
Don’t judge the lifestyles or customs of others if different from your own. Listen to opinions you don’t agree with. It’s arrogant to assume your views are correct and other people are wrong. Practice empathy and put yourself in someone else’s shoes.
