thinking about carnival in brazil but worried about gluten

I've been dreaming about seeing Carnival in Brazil for years, and now I'm finally planning a trip to South America—Mexico, Argentina, and Brazil are all on my list. The idea of dancing in the streets of Rio sounds incredible, but honestly, I'm a bit nervous. I was recently diagnosed with gluten intolerance, and the thought of navigating new foods in countries where I barely speak the language is stressing me out. I'm also debating whether I should book group tours or just go solo. I like meeting new people, but I'm not sure if tours are worth the money or if I'd just end up feeling rushed. And let's be real, I'm not 21 anymore—I love a good party, but I can't keep up with wild hostel nights every day. I prefer smaller, female-only dorms in hostels that don't smell like last night's tequila shots. Has anyone managed to find gluten-free options in these places without starving or breaking the bank? And if you've done tours in Mexico, Buenos Aires, or Rio, were they actually fun or just tourist traps? I want to experience the real vibe, not just follow a flag around. I keep reading mixed reviews online, and it's making me second-guess everything. Traveling solo as a woman always comes with its own set of worries, but add food restrictions and the chaos of Carnival, and suddenly it feels like a lot. Anyone else been in this boat? #southamericatravel #glutenfree #solofemaletravel #Travel
