Interesting, hot and busy in August but I still enjoyed it because there were plenty of places to sit there! Yeah!! Lots of shops, music, attractions nice atmosphere.
It does get busy in the restaurants and it is a good idea if you're organised to book a meal beforehand. We didn't and still got a nice meal with minimal waiting time really. We ate in a Mexico place and it was lovely.
I loved Universal Studios and was really glad that I visited. You must go of course but if you're my age just take your time and sit down taking everything in.
