"It's a beautiful castle it's clean has a lot of pretty places to take pictures and hang out the issue was that I requested free breakfast and breakfast was $25 per person around. They charge parking $25 a night which I think that should be included since you're a guest, main elevators did not work. Staff workers are great help answer all of my questions love that it had a shadow to and from Park every 30 minutes."

"Pros: the staff is very helpful, friendly, and efficient. The amenities were great especially to keep little ones entertained if you plan on spending a good amount of time at the hotel. We booked the bi-loft suite and it was a perfect space for my family and in laws to share. Cons: the rooms can use some updating and better cleaning. The bathrooms were a little tight in space. The carpets felt gross, and the utensils & pans (while great to have at our use) were a bit dirty looking despite cleaning them before we used. It can also get a little loud at night from the street, its right next to a fire station so I heard lots of fire engines and many buses going by day and night"

"It was super close to the convention center, which was amazing for days on our feet. The bed was not terrible, honestly. We did sleep pretty well. The price was what hooked us. Great pricing for proximity to the convention center. It does need to be updated badly as it is very out of date. Our door to our bathroom wouldn’t even close so we had to put a trash bin in front for privacy. But overall we would definitely stay there again considering the price is half of what the Marriot and Hilton are."
