I'm not really sure where you are going with this. Between any toiletries, sunscreen, beach wear, elegant wear, casual wear, foot wear, etc there is nothing liberating about not being able to have it. I find it more liberating to have my bottle of wine, snorkel, and anything else that I will need to not pay exorbitant prices for inferior products. We unpack and everything we have is there for the week. It really isn't a problem in the slightest.
If you want to move down to a carry-on, or share one or a larger suitcase with someone else, I have done that plenty of times. Some people absolutely overpack, and that I understand as a burden.
Just be honest with us and tell us you want to save on luggage fees.
