You can travel to Mexico without speaking a word of Spanish, especially if you enter the tourist places of Mexico like archaeological parks, beach resorts, hotels and health spas; in these places the staff working for you will speak English to some degree, since knowing essential phrases to being pretty fluent.

Nevertheless, also you can find some places where you will have some problems with the language if you do not speak Spanish, principally in Mexico’s interior and outside of main cities, but it is not a general rule.

If you speak a little (even at a basic level) Spanish, you will get more from your experience when you want to enjoy Mexico's key attractions; the advantages to consider are a better contact with the local culture, customs and delights of the country; good reason for learning Spanish.

Obviously the Spanish in Mexico is comparable to the Spanish spoken in Spain, but the accent is dissimilar, and several words can vary considerably; however the basic language is the same.
