Disappointed in my travel photos

I just got back from six weeks in Japan and going through my photos I’m really disappointed. Most of my photos were shot in midday because that’s when a lot of tourist attractions were open. As much as I would’ve loved to shoot places like the the golden temple in golden light they were only open after sunrise and closed before sunset. As a result the majority of my photos are flat and dull. The only pictures that really turned out were wildlife photos and those could’ve been shot anywhere. I came back feeling like I don’t have any photos that actually captured Japan! Not to mention there were always crowds and most places had you on tight, restricted routes through places that made interesting angles almost impossible. I felt like everything was just fighting against me. I also feel like I didn’t take enough photos. I barely filled a 64GB card the entire trip. How normal is this feeling? When you come back from traveling or a vacation how many actually good photos do you come back with? Do you feel like you truly captured the trip? I can’t help feeling disillusioned. It’s hard to take photos when your time in these places is limited, I feel like if I could spend a month in some of these places I could capture them in different light and moods but the reality is often very different. Sometimes it feels like the photos you see online and that you want to recreate were only possible because they had special access or they just got really lucky with the weather and light. Anyway, what’s your thoughts and experience?
