On my first trip to Europe as a backpacker I was given a sound piece of advice that I’m honestly still not always great at following: Don’t fret over the cost of attractions. Recognize that you may never visit again and the cost of seeing something that is a little over your budget is much cheaper than going home and living with regret for years that you didn’t do it only because it was a few dollars more expensive than you had planned.
I still struggle with this occasionally. I sometimes get so caught up in the moment of saving money that I forget that I am on a holiday and this may be the only time I ever visit. Given this propensity of mine, I find that city savings cards aimed to save travelers money are often good bets for me. This allows me the ability to see more than I would pay for as individual admissions and allows me to let go of the saving money stress for just a bit!
