I think that if you have a trusted bird sitter that it's a good thing for her to stop by and re-fresh his water and just make sure everything is okay.
If he's social and she and you are comfortable letting him out it's good for him to get some out time.
I think it's always a good idea to have someone check your birds at least twice a day even if it's to just re-fresh the water bowl and make sure that nothing has gone wrong. I.E. bird gets ill, cat gets out or anything else that might go wrong.
Better safe than sorry!
