The English Wikivoyage has reached a consensus that the current default image size is too small, and rather than manually setting the size to 300px for nearly all images (which was proposed), we are requesting that the default be changed to 300px.

Since this is Wikivoyage, with only 32,000 articles, and an average of 10M page views per month, none of the server-destroying side effects that would be involved in changing the size for the English Wikipedia (200x as many articles; 25,000x as many page views) are relevant.
