yeah the Sundial isnt the best if u are afraid of heights. I dont like them and didnt think about the elevator that goes to the sundial is on the outside of the building and is Glass so u can see the ground get further away from you and at the top it does shake a little (wind) before opening. once in the restraunt u feel fine, u dont notice any movement and the floor rotates so slow it took almost an hr to do a complete circle
