Spa Day refresh

In my opinion Spa Day is the least impressive Game Pack, it is basically a pack with a new skill complete with a new lot type and gameplay objects for that skill, that's not me saying that it's bad, but Outdoor Retreat in comparison added a new skill, rental lots (now base game), gameplay objects associated with the theme, as well as a new world, so everything Spa Day has plus a new world essentially. Saying that, Spa Day also feels very much complete in my opinion, the pack serves it's purpose of providing a spa with related activities, what more could they do? Only thing that comes to mind is making it an available ownable business like restaurants and vets.
