On the Yorkshire Memorials site, I think it would be best to change the link rollovers a little. In their over state, they blend in too much with the background. Otherwise that site looks pretty good.
I agree with Magicman. If you really want the gradient, put the links on a background so you can still read it easily.
As for the Breece, the availability page just displays blank calendars, but perhaps you are not done coding this section yet.
One suggestion on the Breece site: I don't know if you can do this or not, but it might be nice to have some interior photographs of the rooms than just the room layouts. I also would like to see the room layouts look more like part of the site. Right now, it looks like they were just quickly scanned in and thrown up there. I might try tracing it in Illustrator or another vector editing program and then importing to the website as a .png. That way you would get transparency around the drawings, but not have the halo that gif images leave. Also, you could just put in the room you want to show rather than the whole floor.
One more thing about Breece: it is kind of difficult to read the text. I like that the background is the photo of the hotel, but I might try a combination of selecting a thicker typeface and lightening the background slightly maybe put in less contrast.
Anyway, a great start and I'm sure your clients will be quite happy.
