To add to the point above: memory is huge! I love the SanDisk Extreme Pro 128GB SDXC V30 for its reliability. Here's a quick comparison:

• SanDisk Extreme Pro 128GB SDXC V30: Fast and incredibly durable.
• Samsung EVO Plus 128GB SDXC: Fantastic budget alternative tho slower. Grabbing two 64GB cards is smarter than one big card just in case. Also, get a Tiffen 58mm UV Protector Filter to protect the glass. Italy is gonna be amazing!

Congrats on the T7! Italy is gonna be incredible but yeah, that stock neck strap is basically a torture device. You should definitely look at the Altura Photo Rapid Fire Camera Neck Strap instead. It distributes weight much better across your shoulder. Since you're worried about the budget, I suggest grabbing the BM Premium LP-E10 Batteries and Charger 2-Pack. They usually have about 1020mAh capacity which is plenty for a backup. Be careful with just one battery though, especially if you're using Live View, which drains power like crazy. For storage, make sure to get something like the SanDisk Extreme PRO 128GB SDXC UHS-I Card V30. It has 200MB/s read speeds so you wont be waiting forever to view photos. A 128GB card holds thousands of JPEGs so you'll be fine for 10 days. To stay stealthy, maybe grab the S-ZONE Water-resistant Camera Insert Case and put it inside a random messenger bag you already have. Total cost should stay well under $150 if you shop smart!

Had a moment to think about this more and honestly, I had a pretty disappointing experience when I first started traveling with my Rebel. I tried to save some cash by going with a bunch of generic accessories and unfortunately most of it was just a headache. I bought this off-brand bag that was supposed to be stealthy, but it felt so cheap that I was always worried the bottom would give out. It ended up being way less reliable than the name-brand stuff I eventually switched to. A couple of things that really let me down:

• Generic batteries often dont hold a charge nearly as well as the official Canon ones, which is a huge pain when you're out all day.
• Those cheap foam inserts for backpacks were not as good as expected and basically just took up space without actually protecting my gear from bumps. Just so I can get a better idea of what you actually need:
• Are you mostly worried about the physical weight on your neck or just having the camera accessible quickly while you walk?
• How many photos do you usually take in a day when you're out exploring locally right now?

> Do I need extra batteries or do they usually last a whole day of taking pictures Building on the earlier suggestion, I am usually satisfied with one battery for a day of stills. Using the rear screen for everything drains it much faster tho. Are you planning to use the viewfinder mostly? Also, for memory, are you looking for one high-capacity card or several smaller ones to swap out just in case?

Found this thread while looking for some travel tips myself and man, I feel your pain with that neck strap. When I went to Rome, I was so paranoid about pickpockets that I almost didnt want to bring my camera. I learned the hard way that looking like a tourist with a flashy camera bag is a bad idea. I would suggest being really careful about how you carry it. Here is what I used to stay under budget and keep my gear safe:

• Tenba BYOB 9 Camera Insert vs a standard camera bag. I really prefer the insert because you can put it inside any old beat-up backpack you already own. It is way more reliable for theft prevention since it doesnt look like it holds expensive gear. Plus, cheap dedicated bags for under $50 are usually pretty flimsy.
• Lexar Professional 1066x 64GB SDXC UHS-I Card vs cheaper generic cards. I had a cheap store-brand card fail on me in the middle of a trip once and I lost every single photo from that day. These Lexar cards are much more reliable for just a few dollars more. I would grab two 64GB ones instead of one massive 128GB just in case.
• LensPen Original Lens Cleaner vs using your shirt. Seriously, dont use your shirt to clean the glass... you might scratch the coating or just smear oils around. This tool is tiny and fits in a pocket. I once left my bag on a train seat for two seconds in Naples and nearly had a heart attack when someone bumped it. Just keep your bag between your feet or in front of you on the metro and youll be fine!
