....our family tradition has always been to take that mid-day break, and head to the waterparks(alot of folks dont see this as downtime, but keep on reading).
TL, is a wonderful way to relax, IMHO. I have yet to set my behind in any chair there, they are always gone when we get there....so, first things first...go get a LARGE locker, everyone already has the suit donned because we stop at the resort first.....take all the other stuff(with the exception of the disposable waterproof camera(get one, you'll love the pics you'll get of your kids having a blast)and head directly to the lazy river....wait for a tube thats empty(should take you all of 15 seconds to find...the double tubes are harder to find, but you'll get one!!
Get your child situated(dont worry, take your time....the CM will even help you get settled if you need another hand, and even some folks who are waiting will help you out as well...if I see a mom or dad struggling to get the kid all set I usually try to help out)...get on that tube, and lay back...enjoy yourself, and DONT GET OUT until you have gone ALL the way round at least once.....you wouldnt believe how relaxed you'll be..it takes approx. 20 minutes to go around once...if your son then wants to do something, find out which 'stop' is closest to the activity(why walk when you can gently ride there)...and most of all, take you time to unwind!!!
As far as the time you'll be arriving, we usually go at around 11/12....stay till about 3, and head back to the resort to go to whatever park we want to see in the evening...I know that when we leave there is still a group of people coming in, but just the same amount of folks leaving.
I think that the waterparks hold true...most folks take the waterparks as a break...and from what I have seen, its three major sections...those who arrive at opening, stay till around noontime, those who arrive at noontime, leave at 3, and then those who arrive at 3, and leave at closing.NOW....this is only observation, but it seemed to be there were lots of folks coming and going at these times.
Whatever you choose to do, its going to be wonderful...just remember to take your sons pace, let yourself relax, and enjoy the park.
As another posted, TL does seem to be more set for those with the younger kids, while BB is geared to the older set......again, its just an observation....but what I do know from experience, is that I and my wife feel like we've got plenty of time to unwind at TL, while at BB we feel that we need to always be active.....maybe its the themeing??Not sure, but I have seen others post similar reactions.
