Hi from north of the river, this is what the P&O website says and it looks new.
Any guest who is a full-time wheelchair or mobility scooter user or requires the use of their device inside their cabin, must be booked into an accessible cabin, selected Suites or Mini-suites that provide the space and features required to suit guest’s needs. If you tell us (on your on-board needs questionnaire) that you will be bringing mobility equipment and the cabin you have chosen is not a fully accessible cabin or selected Suite or Mini-suite, there may be insufficient room to manoeuvre your mobility aid. Therefore, we may need to contact you to discuss other cabin options.
This is defiantly a change and refers to those who need to move around the cabin using their chair. Perhaps this is what the sales person has seen and has got it wrong?? However if you need the chair in the cabin you would need an adapted cabin anyway.
