Should I do a week long, one visit per day with a 4-5 month old kitten?

I am a cat owner and my adult cat struggles with just one visit per day from sitter. Is it safe for a kitten about 18 weeks old, 4.5 months to only have a person change litter box and feed and play for 30 minutes once per day for 7 days? I think other people have turned this person down already. He is obviously a new pet owner and new to Rover. I need the work but wonder how hard this will be for the cat. I would end up spending more than 30 minutes or feel like I needed to extra visits for the cats sake? Help I need to either agree to a meet and greet tomorrow or turn him down.
