This was our FIRST RS tour in 2022. We got our spots last minute... *5 weeks before, and simply showed up! We packed light, per RS Travel/Pack lists, in a carry on and backpack each. NO REGRETS.
Don't worry about the other details. RS does all of that for you! You'll get language handouts for each country, and practice before you arrive in that country.
We're preparing for our 3rd RS Tour in Sept (Best of Adriatic). Greece was last year. Great brands for you will be Eddie Bauer, Athleta, Nike, Under Armor, Columbia, Patagonia, even Chicos, and other "athletic" brands. They are built for activity and easy care/dry. DO check resale shops... you can save on these great durable brands too! (Ladies, check clothesmentor.com, as they ship!)
Pack using "capsule" thinking, every bottom gets 3 tops to rotate, and don't forget a scarf... also buy one or 2 as souvenirs! GET the packing cubes! Pack a couple of outfits together, makes is easy on the 1-2 night stops. 2 pair of shoes... comfy/stylish tennis shoes and Birkenstock or stiff sole sandal (NO flip flops, unless they are for the bus & hotel only)
*Oh, and a packable duffel bag to bring back "extras"! I put dirty laundry in mine (checked it coming back), and the good stuff/souveniers in carryon! (Search YouTube to find ladies that share capsules for your age group) There are many! Also, FB has Travel Fashion Girls... can be overwhelming, but a gold mine of info! *I will Never not go without noise cancelling AirPods! Great for on bus days or other noisy situations. Hubby did, and was always borrowing one of mine the first trip :(
DO get the foldable hangers (amazon) and "ladder" rope to hang laundry in your room, and the Breeze laundry strips! *Giant ziplock bags make great laundry wash basins... shake and wash!
PREPARE to meet some great people! We have six of us that met on that first trip, and are forever friends, and have traveled RS Tours again and again! Be open to new experiences, and enjoy the culture! RS does an outstanding job, and you'll be amazed at the "over the top" experiences, and bonus things you'd never imagine!
*TAKE lots of pictures, and have someone set up a group photo page to share in the cloud, as some of those photos might be treasures you missed a pic of!
ENJOY!
