Sporting Events- My favorite type of activity to travel for or to attend while traveling! My experiences include the Women’s World Cup 2015 and the French Open 2017. Also many American sporting events! While sporting events can be a more expensive activity, they are worth the bucket-list experience if you are a sports fan! Some tips on getting cheap tickets is waiting till the last minute, literally the day before or day of, but you also have to be okay with the possibility of not getting a ticket at all and not going. So, if it is something you 100% want to go to I would not suggest this option. More of a great opportunity if you are traveling and come across a sporting event going on in that location.
Scuba Diving- I am a recent PADI certified scuba diver. Scuba diving is a great activity to get into if you travel often. It can be a bit pricey if you get certified in the US, so I strongly suggest going somewhere else (Thailand for example). Once you become certified the hobby can become much more affordable. To become certified it is a 2-3 day course and can cost anywhere from 180$-700$ US dollars depending on where you are in the world, I got certified in Sicily, Italy where it was rather inexpensive compared to the US (I paid around 250$). I have also scuba dived in Thailand, and they have the cheapest rates I have seen to get certified (180$) as well as many great beginner dives! Thailand is also great for experienced divers as well. And I know you may be thinking, if it is so much cheaper then is it unsafe? And to be completely honest with you I felt more safe with my instructor and the company I dived with in Thailand compared to in Italy. Not saying I felt unsafe in Italy, just that the instructors were much more professional and more helpful in Thailand. The equipment was very good in both locations as well, so I do not think you need to worry too much about it being “unsafe” just because it is cheaper. Just make sure when you dive you are always with a PADI certified company, instructor, etc. If they meet PADi requirements, then no matter where in the world, they should always meet those standards.
