Since most people are telling you whether they think it's worth it, or not, I am going to give you some tips just in case you do not think it is worth it to help you out.
- I recommend going Wednesday, Thursday, or Sunday.
Wednesday and Thursday are weekdays and have less of a crowd, as well as are less money. Also, Sundays I would recommend if you can only do weekends, as Sundays (in general when it comes to the parks) are less crowded, since typically by Monday people have to go back to reality / work / school.
- Pick a date as soon as possible.
I cannot state for a fact, but I would imagine closer to Halloween it's going to get busier and busier. However, I've been told in September in general is not too crazy crowd wise. So, if you cannot make it by the end of the month (which is only a few days away), pick a date as soon as you can away from Halloween.
- Go as early as possible.
Probably something you'd assume already, but just saying. I've been there a couple of times while it's still light out (not much of a scary vibe), but wait times manage to be not too drastically long for a little bit. Also, I've been there in the past when they usually let guests in early before the official time starts. I have no idea if that is always the case, mostly the case, or rarely done, but in the few times I've been it's always seemed to happen, but it's been a couple of years since I've went. Which would be a good advantage.
- Know what you want and where to go.
Once again, might be already assumed, but it's probably a good idea to have a good idea on what you want to do, where to go, and move with a purpose. If houses are really important to you, but you want to enjoy the little things as well, you can always enjoy those little things later. Also, if you want to do it all, or most of the haunted houses, you got two options. Go with the first you see (which is from the entrance down to New York), or cut through Hollywood BLVD and go to the other side of the park (since most people wouldn't be going that way). Entrance to New York are four houses, where as Hollywood down to near MIB has five houses along the way.
