I just wanted to say, I stayed in one of the IzZzleep capsule at that airport in Mx City. They are pretty small. You 2 may have squeezed into one but you definitely would not have been comfortable or gotten much sleep. Especially if either of you is even the slightest bit claustrophobic.

They are only about as wide as a single bed, 47.25 inches or 120 centimeters wide, 79.33 inches or 201.6. Centimeters long, and just under 4 feet/122 centimeters high. I know I'm not a small guy, being 6'3.5"(75.5"), I float between 225-240 pounds. To give you an idea, I can wear anywhere from size 36 to size 44 US waist by 32-34 inseam US pants, and anywhere from Size Large Tall in some T's Muscle Shirts,and Long Sleeve/Polo shirts. But I'm definitely more comfortable in 1xlt to 2xlt T shirts, and since I also have a relatively big Chest, Upper Back, Lats, Traps, Shoulders and Arms I tend to wear 2xlt-4xlt button up shirts, and tailored dress shirts. My waist is actually only 33.5 inches. But since work out regularly, & dont skip leg day, my Hips, Glutes and Quads absolutely will not fit in 34 pants unless I want to look like I'm wearing yoga pants lol. More and more my sizes depend on manufacturer and fit style. It seems like none of them are true to size anymore. Even different designs labeled with the same size from the same manufacturer frequently fit different.

My measurements that really matter for the capsule are my height & that I am just over 28inches/72is centimeters wide from outside shoulder to outside shoulder when laying on my back with my arms at my sides. With the top of my head touching one end of the capsule, & pointing my toes like when you stand on your tippy toes I could touch the other end wall. If I spread both my elbows out to my sides, I had no problem touching both sides with them. When sitting up with my back against the wall opposite the TV to watch the local news, there was only like 5 to 6 inches from the top of my head to the ceiling.

Infact I roll to adjust my sleeping position. I sleep between flat on my back, both sides and half on my side half on my stomach with one knee out in front of me or with a pillow between my legs. Unfortunately I've had 6 surgeries on my lumbar spine and it doesn't like being in 1 position more than about 45 minutes to 1 hour at most. I do most of my moving subconsciously while still mostly asleep. But with the limits of the inside of the capsule, I woke up multiple times after my knuckles or elbows bumped a side wall.

Jamie, you don't appear to be a huge guy, or even as big as me, but you also don't look like one of those tiny guys who could play a game of racquetball with a street curb either, so even as small as Princess is I don't think the 2 of you would have fit in there comfortably and gotten much if any sleep. Maybe if you both slept on your sides, with your heads at opposite ends, and Princess didn't mind your feet in close proximity to the air she was breathing you could have swung it for a short time. I hope they were understanding and didn't still charge you. But I'm a traveler and have had to go through my credit card fraud department more than once with unscrupulous hotel owners.
