Personally, the wife and I plan on at least 1 long vacation to a foreign country per year. This usually will run us about $5K or so, but we are DINK (dual income no kids) so our budget might be a lot different than yours.
Regarding cable TV - I cut the cord over a year ago and couldn't be happier. Our media hub right now is a Sony PS3, which has turned into the swiss army knife of digital video. I used to pay over $150 a month for cable TV plus all of the movie channels, but now, our home entertainment budget is like this:
One-time (fixed) costs:
$299 - Sony PS3
$1800 - LG 55" LED TV
$500 - Onkyo 7.1 surround sound receiver with speakers
$79 - Logitech Harmony One universal remote
-------
$2678 total one time costs
Monthly costs:
$29.99 - Cablevision Internet only - 20 megabit down/2 megabit up
$22.25 - Netflix subscription with 3 out at a time, Bluray upgrade and online streaming
$9.99 - Hulu Plus subscription - I heard they will drop this price to $4.99 soon
$3.33 - PSN plus - Forgot to add this earlier - it is $49.99 right now for 15 months of PSN plus which gives you access to Hulu Plus.
--------
$65.56 total monthly costs
This has dramatically improved our entertainment while cutting costs. The PS3 now has Netflix with 1080p/5.1 dolby digital streaming as well as Hulu Plus with 720p streaming. It's great not to have to worry about whether the DVR recorded your show or not, but still have access to all seasons of past shows.
We get Blurays of the latest DVD releases from Netflix, which look amazing on a nice TV set, and what's even more important - with a decent universal remote even the wife can figure out how to turn everything on and watch her Desperate Housewives reruns without my help.

They weren't kidding when they called it the Logitech "Harmony".
To more specifically answer your questions - I would say I consider vacation and entertainment expenses as "pleasure" This includes eating out, travel, and things like movies or TV. We budget for them and don't have a fixed budget, but it probably ends up being about 4-5% of our total income.
