Every time I've stayed in a handicapped accessible room, the tubs had bars & hand held shower sprayer. I bring my own shower chair because the resort may not have one for you or it may not be the type you need. I have a transfer bench type that comes apart & fits in a large suitcase. I feel like that set up is much safer than a roll-in shower. You can just swing your legs over & you're on dry floor. I've never noticed grab bars in a regular room.
