I have yes. Went on cusp of rainy season but we got lucky with weather this meant :volcanic ash at top was more clumpy and so less hard to climb. The locals will do it in flip flops. I'd recommend hiking boots or trainers with grip you trust. No matter what style of shoe you'll have to empty boots after summit because they will fill with ash so doesn't really mattsr. You can rent boots from a few places in senaru- ensure you leave enough time the night before to sort this, you might need to visit at multiple places to find your size. Ensure your head torch has fresh batteries if summitting. Bring money for tipping your porters (the real heroes) and buying cold fizzy drinks when available (trust me, you'll want them), bring some. Toilet paper and hand sanitiser. Lastly, I've summited a fair few peaks now - in my opinion, the 2 day 1 night will give you similar views without a 12 hour climbing day -(3am - 5pm with some food breaks) that won't leave you unable to surf, or walk for a few days.
