E.P.
Bob Jones Nature Center in Southlake - - hike, meet animal ambassadors. Or Great Wolf Lodge in Grapevine: Can check in the day before the party, can use the waterpark until close the next day after you check out of room. GWL is expensive. Can only buy the same number of extra waterpark wristbands as the number of people that spent the night in your room. Example: if each brought 1 friend to spend night - - and 6 people total in room - - then you could purchase 6 additional wristbands for the waterpark. Each wristband is over $30. Might limit it to one friend for each anyway - - since it would be hard to keep up with more than that in the waterpark.
