hhn hollywood

[LOLA2]

Have been going to HHN orlando past 8 years, I am getting curious about hollywood and am thining of giving it a try. Actually both fly to California for 3 days (hit DL also) then fly to orlando. anyone ever do this? If so how did it go? what are differences? Is there a stay and scream - get into park early and get a headstart? We have always bought express passes in past. worth it to get them there? Has anyone been to Knotts Halloween event? How is it comparitively have been to fright fest, howl o scream and of coarse HHN.

Thanks
