Obviously will depend on a number of factors like destination, but generally people usually try to stay within a certain range.
Back in the day I'd look for the best hotel I could find for ~$150/night, and if I couldn't find anything good I'd hop onto Hotwire or Priceline. Over the years I've found lifestyle creep has slowly inflated that to the point where I'm currently planning a trip to do the PCH and finding my hotel bookings at $230/night on the low end and $400 on the high end (avg $290) with anywhere up to $70 valet fee (San Francisco) on top.
Starting to feel guilty as I know some well off people who stay at Holiday Inn's everywhere they go, but OTOH someone on here mentioned they spent $20k on their PCH trip.
Curious to see where my fellow ballers stand.
