Best day spa in Orange County?
Though this should be obvious to those clued in enough to provide a decent answer, a "day spa" is full service with: robes, pools / baths, steam room, snacks, etc.

By "day spa," I also mean a spa you can access WITHOUT having to purchase a service.

I assume that those who would answer this question have had birthday celebrations, bridal showers, etc, that would qualify for experience. So I would appreciate your honest reviews.

And I would also assume that those who enjoy leisure travel or other expensive purchases have at least had some local spa experience and will not find my question "indulgent." This is, quite frankly, a normal inquiry.

Please assume that I have done adequate research on Google and am not an idiot.

Please recommend to me a lovely day spa in Orange County or San Diego that offers access without having to book a treatment, massage, etc.

How much is entry and what sort of perks do you get once inside? Basically, what should I expect for the price I pay?

I'm looking for something that is uber plush inside and a-list quality. For example, Qua Spa in Las Vegas was spectacular, for entry. Something similar in quality is what I am looking for.

Pictures, personal details, extra perks or quirks, etc, are necessary to be of decent help. Thank you.
