We have never used them, but I understand that CareVacations will rent and deliver a hospital bed. Not sure of the quality of the mattress so you may want to take an overlay if you are prone to pressure ulcers. My mother has an adjustable bed at home, but we just use the ship's bed...she misses her bed from home, but we make it work because it is easier. We have had to have the extra mattress a few times to make the bed high enough for us to use our travel lift appropriately, but this has not caused a problem for us.
Any nurse who assumes that everyone who uses a hospital bed is sick does not know much about disability. Hospital beds make life easier for both people with disabilities and those who provide their care. Severe disability is not an illness...many people who have significant disabilities are in better health than a lot of AB people I know (I am a rehab nurse in addition to a part-time caregiver for my mother who has tetraplegia due to MS).
Jim, you may want to avoid using all caps. On the internet this is considered the same as shouting and it is also difficult for many to read.
