Here's what I'd suggest: look at the schedule (and for what's not out, look at a previous year's schedule) for when you are going. In February, some of the nighttime shows will probably only be running certain days. Figure out which ones you really want to see, and then determine whether you want to visit those parks on those days. If the answer is "no" - then get a hopper, and if the answer is "yes", then skip it... In particular, if you want to see both Fantasmic and the Star Wars Galactic Spectacular, then think about whether you really want to spend two whole days in DHS, since that's probably the only way to see them both without a hopper.
On one of our trips, we had free park hoppers as part of a package. I think we used them one day total. We've never bought them since, and for the most part have never missed them. Even though we take a break and could hop, we almost never wanted to do so. In the old fastpass system, it was a disadvantage to hop (since you could use passes collected during the day at night). However, this last trip, we really missed them. Disney did their "release info just 2 weeks beforehand" deal and changed the timing for the Star Wars fireworks/show, so that it collided with Fantasmic. We could have adjusted so that we could see both if we had had a hopper (or if they'd announced early enough for us to switch all sorts of other stuff around).
One more thing to be aware of that caught us (and might catch you): when Disney raises
ticket prices, the cost to add on to your ticket is not just the hopper option, it is the difference between the new ticket with the hopper and the old one without. On our most recent visit, we found that this was going to make the hopper option too expensive (for us) to add on last minute. Instead of $68 it was going to be over $100 each. Disney often raises prices in the early part of the year, so if they do so before your trip, you could be in the same boat as we were.
A couple of other reasons to maybe get a hopper:
- We like to take an afternoon break and then in the evening return to a park/resort for dinner (plus sometimes one or two "headliner" rides, and/or a show). Epcot can be a good place for dinner, even if you spent the day somewhere else, and that would mean a hopper.
- In addition to the strategies some others mentioned, I know people who go to the Early Entry park, but just for Early Entry (and maybe an hour after), then switch to a different park. They get FPs at the second park. The usual advice is to skip the EE park, but if you only go for EE, it's the best of both worlds.
