The Bubble Luxotel was the perfect accommodation for the desert if you are not up for staying in a Bedouin camp.
Pros: The rooms were quite nice as far as vinyl bubbles go (or so I imagine), the beds were legit, shower did the trick, and laying on the hammock outside the bubble to gaze up at the stars was quite nice.
Cons: buffet dinner and breakfast were both really underwhelming, and there’s a decent amount of light pollution around or from the bubble hotel itself, so you don’t get the darkest of skies for stargazing (not really sure if you get that from camps within Wadi Rum either).
We really debated between staying in a bubble hotel vs with a Bedouin camp. In the end, as this was the last night of our trip before lengthy travel home, we decided a good bed and a shower were the most important things to us in choosing the night’s accommodation. In sum, if you - like us - are debating between bubble or camp, I’d suggest bubble if your top priority is a comfort. If great local food and stumbling out of your tent into a wilderness of stars is more important to you, I’d lean toward trying a camp (we didn’t go with this option can’t speak authoritatively on this).
