I am confused because you started another thread stating that you WOULD require assistance for your Dad? " Dear Dad is going to have the terminal staff wheel him through security and check in and then ship staff will take over, that's the only time he'll need a chair, for the rest of the trip he can use a walker, I can carry it on myself, but wondering if it can be checked?". Not for nothing and a little unsolicited advice, I have started using a mobility scooter on my cruises and it is the best money I have ever spent. Obviously, I don't know your Dad's limitations, but remember, the ships are three football fields long. Is he really capable of walking that distance with his walker multiple times a day, waiting in lines for elevators, buffets, etc? I've rented twice and am looking to buy now. I used Scootaround and they were fantastic. I originally booked for one week, using the USCRUISE discount code, my rental was $225 for the week. I added a second week before I cruised and that only added $25 to my price! While on the ship, I added a third week and Scootaround only charged me an additional $14. Needless to say, I was thrilled. Anyway, good luck to you and your Dad.
