A little preparation goes a long way.
Make the trade-off explicit before comparing itineraries.
Option to discuss: broader coverage
The Shanghai, Suzhou, Wuxi, Wuzhen and Hangzhou base outline offers varied scenery, with repeated moves and a full second day. Look at the daily structure, not only the names.
Option to discuss: fewer moves
Propose focusing on Shanghai, Suzhou and Hangzhou, reducing Wuxi or Wuzhen to make room for stays, meals and rest. This is a direction to price and confirm, not an already available same-price package.
Compare the actual change
Compare hotel changes, city transfers, main daily visits, room types, meals and total price side by side. Fewer attractions need not reduce cost proportionately; private transport or better rooms may increase it.
