If you want to be sure to see all seven of the haunted houses at HowlOScream at Busch Gardens Tampa, your best bet is buying a Front Line Fear pass. It allows you to use an express line seven times, which means you can use it to see each house once or to do your favorites more than once until all seven slots are used up.
Each year I see people using their passes very ineffectively. Considering that they cost $40, or more if you include the roller coasters, I want to pass along two important tips to help you get your money's worth:
1) Do not come to the park early and line up in the express line. This is one I see people do all the time, and I'll never understand it. You can enter the park for HowlOScream at 5 p.m., and the major roller coasters stay open until the event starts at 7:30 p.m. The lines are very short, so it's a great time to hop on rides like Cheetah Hunt or SheiKra to your heart's content.
Instead, people come in get right in line for a haunted house. Worse yet, if they have a Front Line Fear pass, they get in the express line. They stand there for half and hour or more, depending on when they arrive, when they could be enjoying rides instead. The express line is long early on for that reason, so they're much better off spending time on the roller coasters until it dies down. Once the foolish early birds are through it, the express wait is shorter and you didn't waste any time.
2) Do not use Front Line Fear if the house wait is 15 minutes or less. Why on earth would you use your Front Line Fear pass when the standby wait is short? I see people use it when the wait is as little as five minutes. It's much smarter to go through the standby queue and use your Front Line Fear later, when the lines are long, to repeat your favorite houses. Just because you have a pass doesn't mean you should use it on every house. When there's no wait for standbys, it makes absolutely no sense.
While I often use Front Line Fear myself, Fright Feast is my favorite way to experience the event. Jump to this article for a side-by-side comparison of these two great ways to skip the lines.
