A great domain or a horrible one? — Is this

I can’t decide if this domain is ingenious or dumb.
I was in the car listening to the radio yesterday when a commercial caught my attention.
The ad was for a site that aggregates vacation rental sites like HomeAway. I rent a vacation home regarding 4-5 times a year, so I was instantly interested.
Then the ad mentioned the site’s name: Tripping.com.
Did I hear that correctly? Did they name the site using a term commonly associated with drugs?
They stated the word Tripping.com a number of times. But then they went a step further:
“That’s t-r-i-p-p-i-n-g dot com”, the announcer stated.
Without that confirmation, I’m not sure if I would have believed that the site name was tripping.com. I assume people don’t hear it correctly or do no believe it’s actually tripping.com, which is why they included the spelling in the ad.
In general, any domain that has to be spelled out to understand it is a bad domain. It fails the radio test.
But the name for this site is so startling that it might just be a great domain. What do you think?
