I get free HH Gold as a corporate thing through work so tend to use Hilton hotels for most business stays. I generally get around 3-5k points per night stayed so doesn't take long to get enough points for a free night or two away for me and my wife somewhere if you pick the lower points rated offers. If you afford popular dates you can often get rooms for 20k-30k points
Conversions offer very poor value in general. Be patient, allow the travel industry to stabilise. Right now, there are a lot of excellent hotel offers for 2021 bookings if you are open to gamble.
