Traveling to 🇲🇽 Mexico soon?

I recommend these travel resources for Mexico that I personally use:

🏨 Hotels: I have found that Expedia and consistently have the best deals on hotels and resorts in Mexico. If you prefer to stay at a vacation rental, check VRBO that is usually cheaper than AirBnB’s added fees!

✈️ Flights: To find the best flight deals to Mexico, I always use Kayak. Remember to subscribe to their price alerts for the travel dates you want. Another great alternative for flight deals is Expedia.

🚗 Rental Cars: I always use and highly recommend Discover Cars because it allows me to compare several car rental companies and view ratings on various factors such as overall value, pick-up procedure, agent efficiency, car condition, and total time taken.

🚙 Cancun Airport Transportation: For the fastest and easiest way to travel, I suggest arranging a private transfer with Cancun Airport Transportation. Honestly, no better way to travel from the airport to your hotel or resort.

🤿 Tours & Activities: For tours and activities in Mexico, I highly recommend using either Viator or GetYourGuide. These websites offer a full refund if you cancel your booking 24 hours before the start of the tour, and they also provide excellent customer service in case of any issues.

🚨 Travel Insurance: I always suggest purchasing travel insurance as a precaution before traveling, especially after a recent accident in a taxi in Mexico. For short trips, I recommend Travel Insurance Master, whereas for digital nomads, Safety Wing is a better option.

📷 Best Camera for your trip: I always carry with me a GoPro, It’s light, compact, takes great video and pictures, and most importantly, it’s waterproof! You just can’t go wrong with one. If you are interested in higher quality video and photography, I always carry with me on my trips and highly recommend the Sony A7IV which I think is the best travel DSLR Camera out there.

☀️ Biodegradable Sunscreen: Remember to include a good sunscreen to protect yourself from the summer sun. I always use and suggest Sun Bum Sunscreen, which is vegan, reef-friendly, and cruelty-free.
