Thats just what they are expecting you to do.... you have buy both of them

While the 300/2.8 is an expensive niche (though one I would buy), Pentax don't even offer a 18-250 travel lens (one I would buy in an instant). That most certainly isn't niche.
They did have an 18-250. It's just that it was Tamron's and they pulled the superzoom pin on Pentax it seems.
In the local (amatuer) photo club I participate in, which are mostly C an N users of course, the newer smaller Tamron 18-270 PZD version is getting a lot of lovin'.
A 300 /2.8 is a special and expensive niche I think it makes less sense these days with better ISO performance.
I say this having never owned or even tried a 300/ 2.8 and being so impressed with my eventual choice of a DA*300/4
but....... comparing 300 f4 to 300 f2.8
SLR Camera Lenses
the 300 / 2.8 is
2.5x the weight to carry around
3 to 5x the cost (so the wallet is not so heavy to carry around)
The 1 stop speed or ISO advantage is minimal with a K-5 or body with similar iso performance.
OK, so the DOF is 30% narrower but a 300mm lens has pretty thin DOF anyway.
The only real advantage I see is if you specifically wanted to use it with an autofocus TC.
A 600mm f5.6 might have an easier time than an effective 600 f8.
Comparing random pictures taken with a 300 f2.8 vs a 300 f4, on average, the sample photos posted with a 300 f2.8 will look more pleasing but IMO this is because the person who has invested in a 2.8 is a more critcal photographer (and also is likely, but not necessarily better than an average f4 user) but they would only post the best of their collection.
I saw plenty of sample pictures and thought, wow i've got to save up for a 300/2.8 but I realised its not the lens that was performing significantly better, it was the person behind it.
I'm glad I went for a DA*300 which I'm still learning and have a ways to go yet. A 300 f2.8 is a big step up just in the handling (and the paying for it).
If I'd found a 300 2.8 it probably wouldn't have left the house yet and certainly would never leave the house without a tripod.
