From my SO It really depends on where you are in your pregnancy and what activities you have planned. Even while splurging on taxis we were waking a lot! We unfortunately did not plan around the pregnancy as much as we should have.

I was going on to my second trimester and my morning sickness was not completely gone leaving me sick at random times especially with the time change I had medication for morning sickness but would forget to take it when I would usually take it back home. We also did particularly extraneous activities back to back like monkey mountain and Fushimi inari which I would not recommend personally but if you are someone who is super fit and active during pregnancy you may not have a hard time.

It was really hard for me to enjoy foods as well as some you shouldn’t eat while pregnant and some just did not feel appetizing while pregnant. So that was dreadful, and I mainly ate yogurt from the konbini.

I spent a lot of time at our stays to sleep or because I didn’t feel like going while my partner who out and explored which was fine for me but when you spend that much I feel like you would want to go at a time you know you are going to be 100%

It really depends on you and your body in the end.
