Design travel guide

I have made a travel guide in Canva in which I did a lot of design work already. But some pages are still a bit messy which I can’t get decent. So in general the look and feel is good, but some pages need to be adjusted a bit to make it better. Mainly pages with a lot of content. It needs to be set up in such a way that I can use it afterwards for other travel guides as well. I will give you access to my Canva document. The content that is on that page should stay in there. There are a lot of the same pages, so they don’t need to be adjusted all, as long as 1 page per type of page is adjusted, then I can do the other pages.
A few examples of pages that needs to be adjusted can be found in the attachment. In total the guide consists of 124 pages, but there are only 12 different type of pages. Whole document needs to be checked to be able to see how many content there is on each page and the page set up can be made for all different kind of quantities of content. There are 3 main pages that needs to be improved, other pages can be checked to see if you can make it better.
