Some things to keep in mind when building for tourists is their interests.
Service buildings provide those interests, just read their descriptions.
Every colonist needs to fulfill one random interest per day.
The list is per colonist and is unique to them based on their traits.
Tourists stay on mars a full 5 days (sols).
So 5 random interests.
A tourist cares about the following interests as a tourist the most.
They will always have these in their list:

• Social
  
• Relaxation
  
• Shopping
  
• Safari
  
• Gambling

Gambling and Safari seem to be the top interests, since the table they come from for tourists weight them a bit higher. Random is not so random after all.

They may or may not have a another trait like Gamer or Fit so look out for those. They are randomly added to the list above.
Gamers need Electronic Stores and Fit need a place to exercise.

They also need a place to stay, eat and get medical attention.

So in general, a Tourist dome, should have the buildings necessary for these interests, and have an RC Safari nearby.
