It would be so much easier if we could put our rooms in the order that we want them in, at least it would be for me..
This is at the top of my "wants" list right now. As those who have a quest kiosk know, vmk lets us move the order of our tasks around via up and down arrows placed next to each task. So handy! I'm hoping vmk adds the up and down arrows to "own rooms" list so we can move our rooms around.
As to how I organize my store rooms, I, too, use the free Skull Rock rooms I got from the Kelloggs Conquer the Sea game. I label my rooms with the word Store - first, then just a few words describing what is in that room. For example:
Store - Halloween
Store - Teleporters - Doors
Store - Crates
Store - Fountain
Store - Water slide ride
Store - Rugs
Store - Adventureland
Store - Small World
Store - Frontierland
I have multiples of some rooms, i.e., Halloween, Christmas, and all the Land shop rooms, and usually have no trouble remembering which Land room holds which items. My rule is, if I have a lot of any one type item, i.e, trees, I put them in a room by themselves. If I have only a few of an item, I put them into the "Land" room according to the shop where I bought them.
I also keep my store rooms restricted to myself and friends, otherwise, I get people coming in to buy stuff from my stores (lol!).
