Ok so there's so many trinkets to buy that are VASTLY overpriced! You'll see amazing indigenous dresses (huipil) with so many colors and patterns. You CAN buy them, you CAN wear them, infact people like it. The colors and patterns mean they belong to a specif area so feel free to ask. Coffee.... omg they sell an amazing coffee in any coffee shop located around the square. Youll see so many locals enjoying the park as well. If you're traveling on Sunday, just a few blocks away, is shoreline church (evangelical non-denomination) to get your spirit going. Entertainment: theres an art gallery, museum of Guatemalan history, and the cathedral that you can visit for free, you just have to sign in a sheet your name and where you're coming from. The Antigua Arc is a few blocks away, go get your insta-worthy picture there 😀 😄. Food: well I would suggest going to a local eatery BUT watch out for the spices, and I don't mean hot ones, it's a combination of so many herbs, peppers, and dry spices that it might give you the runs (I've been running for the past 3 days). Parking; there's hourly parking at around 20 USD so do with that what you will. Street food: you'll see vendors pushing like mini busses and trucks, BTW that's a guatemala thing so take pictures, they sell Popsicles and ice cream 🍦 I just took pictures, no idea of the water or milk used.
