Sometimes they do. Sometimes they don't. Depends on the quality of the visual, depends on the quality of the build, depends on the timing and how much is known or resolved when.
I really do respect opinions and people's dislike of stuff and their saying so. Zero issue with that.
But if you or others are basing it on the fact that you anticipate the finished thing to look worse than an in itself a not great render, you might be at least partly off track.
Don't particularly disagree with anything else you said, as such. Well apart from the claim that there aren’t many new hotels in Britain that are particularly architecturally good looking.
