Visiting Las Vegas while pregnant can be fun, but it is a trip where comfort matters more than checking off every famous thing. This is not medical advice, and you should follow your clinician's guidance, especially around travel timing, heat, walking, food, and any activity restrictions. From a planning standpoint, though, Vegas can work well if you choose calmer hotels, shorter walking loops, good meals, and indoor anchors.
The point is not to do "less Vegas." It is to do a version of Vegas that feels good.

Quick Answer
Pregnancy-friendly Vegas plans often include:
For alcohol-free ideas, read Las Vegas for non-drinkers.
Where to Stay
Choose convenience and calm. Vdara, Four Seasons Las Vegas, Waldorf Astoria, and Park MGM are worth considering because they reduce some casino-floor friction while keeping you near the action.
If you are not renting a car, use where to stay without a car.
What to Do
Shows are a strong anchor because they are seated, climate-controlled, and memorable. Browse best Las Vegas shows. Museums like Mob Museum and Atomic Museum can also work if you pace yourself.
For easy visuals, do Bellagio Conservatory, fountains, Grand Canal Shoppes, and a coffee or dessert stop.
Food Strategy
Book restaurants where menus are clear and staff can answer questions. If you have food restrictions from your clinician, call ahead. Best restaurants in Las Vegas, gluten-free on the Strip, and best coffee on the Strip are useful planning companions.
Heat and Walking
Summer heat can make a normal Vegas walk feel much harder. Use rideshare before you are exhausted, carry water, and do not let the map bully you into walking too far.
For summer trips, read Las Vegas in August and Las Vegas in July.
What to Skip
Skip smoky casino wandering, marathon walking days, aggressive pool-party scenes, and anything your clinician has told you to avoid. Vegas will still be there if you take the easier version of the trip.
