I watched a video last night advocating exactly that. Once your portfolio is "enough" (which is not easy to calculate, but it's just math), redirect retirement savings to spending. The transition to spending on things like travel or long-delayed home projects, or other "someday" items, is less stressful if you do them while still drawing a paycheck. In that situation, you're not jeopardizing any part of your portfolio.
My retirement planning didn't allow for that. My plan was to work until age 70 after hitting The Number. However, the stress became overwhelming a few months before I turned 66. I looked at my portfolio on Saturday, spoke to my financial dudes early Monday morning (confirming my assessment), said "FUCK IT!", got my boss on the phone and resigned. I was short of The Number, but it was still do-able.
I've been lucky. You know that old adage, "A rising tide raises all boats"? Two years in, I've not only blasted past The Number, my portfolio is growing faster than I can spend it. I plan to take a few major trips over the next three or four years mostly because I can.
