49 days in Peru - thoughts on this itinerary?

Late August-Early october.

This is the hardest trip I've ever planned, with a lot of uncertainty in the second half which I've tried to account for. I've been before, about 10 years ago, did Cusco and Machu Picchu and been dying to go back all these years.

I know 49 days is a hell of a lot of time so I've learned from past trips and tried to pace myself. I will absolutely be traveling light until the last few days. This will be a semi-budget trip, hostels and hotels pretty evenly. Tried to make it as low stress, low rush as possible.

Even with 49 days though there wasn't enough time to do everything. I really wanted to see the northern coast, but alas.

LIMA TO CUSCO/SOUTHERN PERU:

Day 1-2: Lima. Not a lot of time here as I'd rather see it at the end.
Day 3-5: Paracas. Ballestas islands (haven't booked yet), see the nature reserve. Mostly relax.
Day 6: Huacachina. Day 7 - Ica, afternoon/night bus to Arequipa.
Day 8:free day in Arequipa.
Day 9-10: colca canyon tour (haven't booked yet).
Day 11-12: Free days in Arequipa. Night bus to Puno.
Day 13-14: Puno. See the floating islands. Would love to hire a kayak and do my own thing.
Day 15: day bus to Cusco.
Day 16: Ollantaytambo, stay overnight.
Day 17: Cusco.
Day 18-19: Hidroelectrica, aguas calientes. Machu Picchu the next day - Circuit 2B and 3A (was sick last time and missed Huayna Picchu - won't let that happen again). Late train back to San Pedro.
Day 20-21: two free days in Cusco.
Day 22: Valle Rojo (haven't booked yet).
Day 23-24: a couple more days in Cusco. Evening flight to Lima.

THE AMAZON/NORTHERN PERU:.

Day 25: Morning flight to Chachapoyas.
Day 26: free day.
Day 27: nothing organised - Kuelap, Gocta falls. Seems like a lot of interesting things to do.
Day 28: free day.
Day 29: Travel to Tarapoto, either by bus or colectivo.
Day 30: free day.
Day 31: Bus or Colectivo to Yurimaguas.
Day 32-33: a couple of free days here, to allow for any delays etc. in catching the slow boat to Iquitos.
Day 34-37: On the boat. Added an extra day - Ideally it hould take 3 but it's the Amazon so who knows. If it gets to Iquitos a day earlier that's fine.
Day 38-39: free day in Iquitos, in case I have trouble organising a tour into the Amazon, or any delays with the boat, etc.
Day 40-43: four day Amazon tour. This i haven't booked yet - hoping to do it locally. Return to Iquitos. Haven't booked this yet.
Day 44: another day in Iquitos. Figure I will have already seen it, but added a day here in case of any problems - tour delays, getting back late. Otherwise just an easy day.

LIMA:

Day 45: morning flight from Iquitos to Lima.
Day 46-48: No real plans in Lima. Shop, stay in a nice hotel (figure I will never want to see another hostel after this lol), decompress, eat some good food. 6pm flight on day 48.
Day 49: N/A - red-eye flight home at 01:30.
