I am really enjoying developing Bottlenecker's idea fully. This is what we should have done:
Sep-Oct 2013: online perusal only probably, find venues for a big "lljkk came to the country" party
Nov 2013: book somewhere within 2 hour drive of most people, send out invites & RSVP schedule to about 50 households (expect max 30 households to RSVP yes). Probably provide all the food, since they are paying for travel costs. People living more than 2 hours drive away probably won't come due to high hotel costs. Finalise food & other details. Do I need to book entertainment, a DJ?, or is just hanging out good enough? No dress code.. or should I? Book it maybe 1-5pm. Cost has got to be at least $1000 without entertainment, but depends who shows up
Friday 4th April: last day of term,
Sat 5th: travel to London & transatlantic flight (£4k) in digs that might cost a mere $1000-$1500 for 9 days if my dad knows the owners again.
Sun 6th: up at 3am with jet lag, any waking time spent glazed over, not safe to drive hours & hours in any direction
Mon 7th-Thurs10th: still up at absurd hours, try to relax & visit with close family, make sure all plans ready for big party
Friday 11th: finally ready for some kind of organised outing
Sun 13th: big party! People keep saying "But why didn't you come for X day instead....?" and me trying to explain how strict English schools are.
Mon 14th: pack, prep to come home, fly on evening flight
Tues 15th: arrive in London, 4 hours to get home from there
Weds 16th-Mon 21st: recover from jet lag
Tues 22nd: start of summer term.
Yup, not impossible. Absurdly poor value for money, but not impossible.
Summer activities would look similar but could stay longer if I could afford it.
