We have a saying in Australia..... "Only bums keep seats! "
I believe that if you are sitting in your seat, and having fun for the entire day, so be it. However, if you leave to go on the Aquaduck, go for some food or even a swim... you have left that seat and someone else can now have use of it.
If you are standing in line for something and you leave your place, then it's gone and you have to line up again. Same applies to the deck chairs.
I think it shows an extreme lack of courtesy, to leave your seat with personal items on it and go for a swim, thus not allowing someone else use of that chair while you enjoy yourself and then expecting it to be there when you return.
Sorry, I just do not get this philosophy and the heated debate it always seems to cause. If you plan on spending the day at the pool or in the pool area, and you claim a chair or two for your family, then it is common sense that one or all of your party will be leaving the chairs throughout the day to go to the bathroom, swim, get food or get drinks. Even to run back to your stateroom to get something -- I do not see these as chair hogs because they are using those chairs ALL DAY.
Same goes for CC -- seriously, you don't expect people to swim or bike or walk along the beach? But the majority of the attitude expressed here seems to be if you do, you must take all your stuff with you and then find chairs later when you return? Obviously none of you have been to the Jersey shore
You claim a large beach area for family and friends with chairs, blankets, food baskets and beach toys. Nobody comes along with their chairs and says you can't claim all that space!
I don't understand why it is a MUST that your bum be in that chair 24/7 while you are there. These are by the pool -- you don't expect people to go in the water? Then what should they do with their stuff, stick it in the corner? Haven't any of you claimed chairs at hotel/resort pools for the day? You are in and out of the pool, going to the snack bar and going back to your seats. Nobody is entitled to move your stuff off the chair(s) because you are still there in the area and making use of the facilities!
You really are entitled to have a place to put your stuff while you swim. Unfortunately, there are those who have ruined this concept and made everyone more self aware of what is now known as "chair hogs". But I think the term has lost its original meaning.
I think a distinction needs to be drawn between people who claim chairs at 6 a.m. and then don't even return to use them until the afternoon or late morning. They are most definitely chair hogs and that seems to be breaking what everyone has said is Disney's rule. But if you go up and claim chairs, go have breakfast and then spend the rest of the day there, then no, you are NOT chair hogs -- you are using the area as intended and getting what you paid for
One person even commented they have their lunch there too!
OF COURSE people will have to leave their chairs throughout the day (if for nothing else than mother nature -- certainly don't want them in the pool doing that
), but they are making use of their chairs throughout the day and not taking more than they need! To me, that is NOT the definition of a chair hog!
If it is that much of an issue for you then get up earlier and plant your bum in your seat for the rest of day. Do not dare leave your chair unattended for any reason...including using pool, grabbing food, towels, drinks, bathroom...etc because someone who is overly concerned with chair hogs will remove your stuff.
