Hi Loopylou,
My colleague contacted the hotels that we use and has come back to me with the following;
Lisbon & Ericeira:
The hotel has said that they do not have any rooms with separate walk in showers, they have "normal" baths which are at least 50cm high and believe that it may be difficult for you to access.
Costa De La Luz:
The hotel that we use has said that they have a "normal" bath and 4 rooms with showers. If you would like to go on to book this tour, we can request a room with a shower - you will simply need to speak to one of our holiday advisors.
If I can be of any further assistance, please do not hesitate to get in touch.
Kindest regards,
Julia
