We haven't embarked our on October trip to Portugal yet, but I'm already thinking ahead for possible trips next year which would either be Mexico City or a European country (Italy, Spain, UK, or Italy could be one of them). But that said, this post/question is about Mexico/Mexico City :)
I've lived in the US for several decades now and never have really visited Mexico except in 2019 which as part of a cruise we visited Cozumel and Costa Maya, but to be honest, I don't feel these types of cruise really give me a sense of the place as the excursions are often too short and superficial. So to me, if we go to Mexico the "usual" way (not a cruise) next year, it would be my "first time".
I know Mexico City is definitely on my list and probably the first place to go just because it is relatively easily accessible and it would be good to see what a major Latin American city feels like. I'd like to get some sense of the place. How long should we stay in Mexico City? For example, is 4 full days enough? Longer? Shorter? Are there any day excursions to places around/away from Mexico City that's worth exploring? We'd still make Mexico City our home base.
We're also not retired (and aren't full of money) so we couldn't spend more than say a week to 9 days on a trip.
As mentioned, we are generally the kind of traveller that like to get a bit of depth with a place. We do not enjoy being rushed from sight to sight or site to site just to say we've done something. That's partly why after my first cruise (the one in 2019) I came to a conclusion that such sea cruises for me is more about the resort-like experience and I should not have hopes for getting to know the places that the ship docks at. So we like to poke around as travellers, walk around, get off the beaten path a little, but also like to at least in part do it in a relaxed way, but not without some plans or itinerary.
So any advice on how long one could visit Mexico City and if there are excursions/places around the city that are worth taking a day trip to? Oh, we don't plan to drive or rent a car. The thought of renting a car seems to be a super hassle, but if you think driving is recommended, do convince me :)
