I'm something of a hoader in that I won't spend miles for less than ~3cents/mile and hotel points for less than ~half a cent per point (both net).
I generally earn ~500k miles per year; and spend at a similar long-term rate, though with ups and downs. I like to keep enough of a buffer to be able to do an unplanned transpac or TATL in C/J on any airline.
I take the family (5 of us) to EU on vacation every 2-3 years in C/J/F, and still have plenty left over; I even spend miles on business trips if the company won't pay for C/J and there is no confirmed MFU avilable (buys good will for the next time I ask...)
On the hotel side, I use points on MRs and for family vacations. I'm hoarding my PC points for the next EU vacation with plans for staying mostly in ICs. SPG points (mainly from SPG Amex) I treat as miles, and hoard to transfer as required - mainly for MFU on airlines I don't use much.
Current totals:

AA~300k
CO ~400k
AS ~100k
Amex ~200k
BA ~100k
plus ~100k spread across other programs
