My wife has limited mobility, so uses wheelchair assistance.Agree with everything said above. On embarkation, just tell the "line monitor" you need a wheelchair. You will be tole where to sit to wait for assistance. Yes, there is sometimes a bit of a wait. For disembarkation, the documents you receive will include insrtructions on when and where to go for wheelchair assistance. Usually off the atrium, probably at Vines. No need to pre-arrange either.
