In general, I love a resort location. I feel like the conversion of stress to experience is a little onerous and stingy in Mothership, especially given that there's such a high chance of a character dying, so I'm always looking for adventures that can do double duty. As an alternative hook, the players could be resting/converting stress when everything goes to hell.
Love the cover art, the color choice, NPC profile pics and descriptions. With the NPCs I thought you did a good job giving them personality in a short space. Mira's broadcasts had me laughing out loud and were my favorite part.
I thought everything was very playable and easy to follow. There is a bit of a video game quality to this where we're clearing rooms with guns blazing which is more "action-horror" than my personal taste and I think it would be a few too many rooms for a one-shot, not that there's anything wrong with that. This is just my opinion, but I think you have a real flare for dialogue and description and the space on the second page my be better served by fewer rooms with more roleplaying fleshed out. At the same time, you've done a great job placing all the necessary details for the wardens to run with it themselves, so I don't think changes are necessary as it works great as is.
