We used the WDW bedrails when DD was little and they were great. On DD's 2, 3 (2 trips that year) and maybe even 4 year old trips, we called WDW and had them note on our reservation that we needed bedrails. They were brought to our room upon our arrival-once they may have already been there before we even entered the room. When we checked in, they always had it marked that we had previously requested them. Don't know if it is true, but we were told that if you request them in advance they are put aside for you, where if you wait until you get there, it is a matter of whether they have any left or not. They were great, and DD slept fine with them. We would put the extra pillows along the sides too, but probably did not need to. We did the parks pretty much open to close, and she was always so wiped out at the end of the night that she went right to sleep in the middle of the bed. She was used to a twin bed at home (with a bedrail)- we tried a toddler bed for about a week but she hated it. She loved getting a "big bed" at WDW.
