Illustrated book about space tourism.
It was a shortish book, but with large illustrated pages, about a future space cruise through the galaxy visiting a number of outlandish planets.
The one illustration I've been able to find was by Richard Clifton-Dey, called Behemoth's World.
Could it be Tour of the Universe: The Journey of a Lifetime: The Recorded Diaries of Leio Scott and Caroline Luranski by Robert Holdstock and Maloclm Edwards? 143 pages, published in 1980. It's the only book about "cruise" featured in ISFDB, that contains the work you attached to your question.
From a review on Goodreads:
The story of a couple who win a tour across the galaxy, and the complications that pile up on their trip. The story is told through journal entries, painted scenes, and various futuristic documents.
Or from Google Books summary:
Two winners of a trip with the first package tour to the Aurora-Magellan Federation spend six months visiting alien planets
Printed version is available in various locations, most notably on Amazon. Alas, no e-book version exists to my knowledge, but it's possible to use search engines to find the works in that book as they're all listed on the relevant Internet Speculative Fiction Database page.
This is what the cover is supposed to look like:
And here are some other works from the same book:
