Usually around end of oct blizzard beach closes and only Typhoon Lagoon is open until they’re both open early in the yr. I can’t recall when that is if after your trip timeframe. So if adding fun option and not using it for other activities such as miniature golf, that could be a downer to have BB closed.
But I know the fun option is pretty cheap relatively now because more ppl want park hopper and guests aren’t buying the fun option as much.
The water at TL and pools are heated to at least 70 deg F. We’re going Sat 11/30 to typhoon but on a single ticket only because it’s a bit cooler and we’re not all huge into the water parks. This trip is more for Star Wars / Christmas festivities.
I love Typhoon. Even if going on crush n gusher few times... who am I kidding, I’ve never not ridden it less than 10+ times in a row. But just napping on lazy river is nice or lounging on the beach by the wave pool.
Some Jan feb - such as 2016, a warm winter, we were in T-shirts and shorts all day. But it can get cold early am if you like to rope drop rides. Think I’d consider doing it if big into water parks.
