Parents of children with disabilities say they are "devastated" over plans to close two residential respite care homes in Hampshire.
The county council has launched a public consultation on its proposals for Merrydale in Winchester and Sunbeams in Aldershot.
Campaigners have described the services as a "lifeline" for families.
The council said it wants to redesign the overnight services in a bid to provide a "wider range of options".
It said it was aiming to develop a "less institutionalised approach" to respite care with services that could give users more choice.
Proposals include offering family breaks, overnight stays with specialist foster carers and home care breaks with a carer staying overnight in the family home.
'Devastated and disgusted'
Melissa Jones' 16-year-old son, Chris, who has autism, severe learning disabilities and epilepsy, and needs two-adult supervision at all times stays at Sunbeams at least once a week.
She said: "For him Sunbeams is the only place he can interact with other children - it's a lifeline. Calling the homes institutionalised is a draconian way of putting it."
Parent Jill Harris said she was "devastated and disgusted" by the proposals and described the respite days as "gold dust" and "life-changing" for her 15-year-old son who is autistic and their family.
A consultation on the proposals runs until 2 October.
The authority said if the decision is taken to close Merrydale and Sunbeams, families would be supported to explore alternative options.
If they close, both sites would be sold.
