Thoughts
I can't comment on the $ amounts not knowing your situation overall. Just insure you are not short-changing your own retirement since you are checking out of the workforce pretty early. I suspect you are very savvy in that area so I am probably preaching to the choir.
As for our only child, we put her through college completely so she came out with zero debt. She also took it easy on us since a public school in that state had one of the best programs in the country for that major, so our costs were minimized. We paid for her wedding, along the lines of $12K or so total, and it was a great affair with about 120 guests at a great establishment. Your figure of $75K is way outside what is needed to have a really memorable affair. I have also floated the two mortgages for the two houses she has owned to date, since I did not want her getting screwed by a bank. The first house she paid in its entirety with interest when she moved, although I didn't want the interest but it was rather what she wanted to do. Her current house she knows that I only want the mortgage amount back with no interest, so that is how we have it set up.
The wife retired at 55 and I joined her five years later at 60. We have a great life, travel a lot, and barring anything unforseen, I hope to leave our daughter a reasonably good inheritance. Bottom line - I don't put a $ figure on what we do for her, we just do what is right in our hearts. Your way, while different, is very generous for your kids and hopefully will be appreciated by them as much as our way was by our child.
