Despite - and indeed perhaps because of - the wealth of written, online and practical information provided, most first-timers like myself with whom I talked felt like fish out of water.
There was not the time nor brain space to fully comprehend the UN set-up, processes and terminology. While women effectively had an equal voice there, some speaking spots needed to have been booked months in advance.
It was also clear lots of negotiating went on behind closed doors and within established networks.
For perhaps the first time I properly realised how shut out people can be - even in a democracy.
It helped explain the likes of low voter turnouts and made me even more aware of the vital importance of education (and of course why withholding information is a powerful tool for many in authority).
Were all women's voices heard, and were all women represented then? No. Was that possible in two weeks? No. Will the Agreed Conclusions make a difference? Not in some countries and not in all areas and they are not legally binding.
Women I spoke to who had attended commissions for years say progress is still painfully slow and women are still fighting the same issues.
Some governments will lead, some will push back and some will be shamed into following.
That, however, is an important aspect of the power of the UN and the group dynamic.
The UN may seem largely symbolic, idealistic and aspirational. Even Secretary-General Antonio Guterres told delegates "we can only act with the instruments we have; we cannot do miracles".
Yet even symbolic moves hold significant power, and where there is global will, there is a way. For some countries even small changes may be life-changing.
While economic empowerment for many Western women may mean equal pay or seats on boards, in Third World countries it might mean providing a village well so women do not have to walk eight hours a day to bring back water for their families, and can stay at home and protect and educate their children.
Despite some of the horrific problems endured by the world's women that were discussed at the commission (sex trafficking, child marriage, female genital mutilation, even stoning in the 21st century, to name but a few) I was impressed by the positivity of the delegates.
It was refreshing to be in a female-dominated and driven decision-making environment. I found it overwhelmingly friendly, supportive, inclusive and non-competitive.
While I had largely expected that, I was surprised to find the same outside the UN.
Every person I met (whether striking up conversation in a diner, confirming locations on the street or subway, or interacting with hotel staff, cabbies or street vendors) was friendly and helpful.
I had expected they might have been sick of tourists, affected by the atmosphere of fear or prejudice, or simply too busy to notice others.
I left having had my own prejudices and preconceptions challenged on various fronts, and largely impressed by and wanting to learn much more about the UN, and determined to do whatever I can to champion the advancement of women.
I think it was a case of' "mission accomplished".
