3 weeks in Peru: can you rate my itinerary

I’m still unsure if I should go to Arequipa, because I usually prefer having more of a base instead of moving around too much, and as a solo traveler I’d also like to meet people and do activities.

May 15–17: Lima
May 18–19: Paracas
May 19–20: Huacachina
May 21: Arrive in Cusco / rest day
May 22–25: Cusco as a base (day trips / meeting people / exploring)
May 26–29: 4-day Puerto Maldonado / Amazon trip from Cusco
May 29 (evening): Back to Cusco
May 30: Ollantaytambo
May 31: Aguas Calientes
June 1: Machu Picchu (9:00 entry) + back to Cusco
June 2–3: Cusco
June 4: Early morning flight Cusco → Lima
June 5: Flight Lima → Home

Does this itinerary look good for 3 weeks, or do you think I’d regret skipping Arequipa? If I do go to Arequipa, I’d probably stay there for 2–3 days at most, and I’d do that whole part by bus. So from Ica to Arequipa by bus and then Arequipa to Cusco by bus, which is why I’m unsure if it’s really worth it.
