Unless you are stuck on travelling down south, save yourself some money and go to mulberry whin in east yorkshire.
Mulberry Whin - Chalkstream fishing chalkstream flyfishing
Superb set up. just over a mile of river with a fishing hut (that include a flushing toilet) in the middle of the beat. The owner (brian, really nice guy) will also supply hampers at lunchtime (home made and damned good).
Maximum of 4 rods, so plenty of room.
It does get stocked with brown trout, but only once at the start of the season and only to replace any fish taken the year before.
There is also the odd rainbow, they escape in from the fish farm up stream.
The main thing for me though is the grayling, absolute monsters. My best from there went 2lb 11oz, but I've seen fish to over 4lb.
Stunning place, crystal clear water and fish all over the place ... they are not easy to catch and succesful fishing requires creaping around, fishing small flies ... basically, wild fishing.
There is also accomodation available on site and other hotels around driffield - Last time i was over there I stoppped at the blue bell, which is only about 15mins from the fishery.

Given that mulberry whin is only £45 - £60 depending on the time of year you go - your budget will go a lot further than if you go south.
The price by the way is not cheaper because it's better fishing down south - it's simply because the owner is a yorkshire man and charges what he beleives is "reasonable" for a days fishing. He had a river test keeper fishing last year who said "if it was mine I'd charge twice the price and double the amount of rods" !!!
