I'm leaving for the Best of Germany tour in less than 2 weeks (!!!). Very excited, and happy to know I can bring my own water bottle to fill up with tap water. However, I've been wondering how easy it is to refill. I have a 32oz that I usually use for water. Big, but perfect for an all day outing. However, might be tricky getting it under faucet in rooms to fill. I have another closer to 16 oz. Lighter to carry in my backpack, not as bulky, but wouldn't be enough to get through the day.
How easy is it to fill up with tap water while out and about? For veteran travelers, what would you recommend? I know I could always find a place to buy bottled water, but would prefer to stay away from plastics as much as possible.
