The International Children's Games are in Coventry this year. My local area
is sending about a dozen swimmers and some staff. They'd like to stay near
London to look at touristy things, close to a good pool, with tube or rail
access. The person-in-charge asked me as I've had some experience over
there
but it's a bit dated.

The first thing I thought of was somewhere near crystal palace - is that
pool still running? Would there be reasonable accommodations for such a
group?

The age range is about 12 to 16 (of the swimmers). Suggestions for things
to do as well as places to stay and swim would be welcome.

As always, budgetary constraints are a factor.
