At this time, a package must include at least two days of park tix. We sometimes do quick weekend trips with a single park day, so those have to be room reservation with separate park tickets.
If you do book a package, it comes with “magical extras” like mini golf tix and some other discounts. We typically do use the mini golf passes as our kids love this, but you may or may not consider this a benefit. On most occasions the folks at Winter Summerland have taken the ESPN passes for golf also or offered that we could use them for golf (as there is typically not anything available at ESPN for us to attend). We don’t typically use the other discounts.
Packages usually also come with plastic themed luggage tags and such.
