One thing not mentioned here is the rather disproportionate price of a day Thistelgorm trip compared to a 3 nights/ 4 days liveaboard. These days you'd be struggling to find the day trip lower then 180 euros and you'll get 2 Thistelgorm dives plus one dive in Ras Mo national park (usually Shark&Yolanda)
I'd say the day trip only makes sense for people doing family resort-based vacations.
