It absolutely was for us, but I think it is kid specific—I have three kids and youngest one REALLY wanted to do it and the other two were not interested so I just took my youngest and that made the price less crazy than taking the whole family.
It’s an amazing experience for a kid who wants to dress up and be a princess for a day. They really roll out the red carpet and make the kids feel special every step of the way, from announcing the arrival of each child to great fanfare, pouring the apple juice “tea” at each table simultaneously, the custom cupcake, and the princess interactions are great. All the children there were kind of in awe. I thought the food (cakes, pastries and little bite-size sandwiches) was also really good and on par with high tea at nice hotels in a city that i’ve paid similar adult prices for. I do wish they had a better selection of teas but most people won’t care about that (I love tea). A lot of the kids price is of course the merchandise and it is nice stuff—not sure I would buy it all independently but it does contribute to making the price more reasonable.
So at the end of the day I go back to the first thing I said: whether it is worth it depends on how much a kid wants to do it. I think for kids who are young enough to truly believe they are going to a princess party and for whom that is a dream come true, it’s worth every penny. I might even recommend it for a more casual princess fan once because it is really well done. I don’t think I’d recommend it for adults or teens/tweens because it is really focused on the kids and making them feel special.
