Great Wolf Lodge Grapevine
An indoor water park kept at about 84 degrees year-round, which makes February and August equally irrelevant. Body slides, tube slides, a wave pool, a lazy river and a giant tipping bucket play structure cover everyone from toddlers to teens. Water park access is included with an overnight stay and this is the whole reason families book it. Beyond the water there is a MagiQuest wand game through the hotel hallways, an arcade, and a ropes course. It is not cheap but it is genuinely weatherproof and one stay usually kills two full days.
