Cancun is the most visited city in Mexico. For many travelers, Cancun is the dream destination. The weather is always nice, it has soft sandy beaches and it's always a good party. Travelers flock to Cancun for spring break, for honeymoons, and even for an occasional vacation in the middle of winter.
There are a large number of hotels, both on the beach and in the city, that offer all kinds of different packages. With so many options, there's basically something for everyone. Maybe a friend of his visited Cancun and Tulum and had a great time. That's why this person decides to book a trip there too, without even taking the time to research what they're getting into.
Maybe they were hoping that Cancun and Tulum would have romantic, secluded beaches that other tourists haven't yet discovered. Perhaps they expected authentic cultural experiences. Sure, you might not want to go to Cancun during spring break if you're not a university student, but if you like to party, Cancun will be a better option for you than other quieter destinations. Sure, there are some historic sights you can see (if you want to take a crowded tour for a high price), but culture is definitely not Cancun's main objective.
Avoid visiting Cancun at Christmas, Thanksgiving and during spring break, as it's a busy time in Cancun. Therefore, before planning your vacation in Cancun, it is necessary to check the current state of seaweed in Cancun.
