We have an early morning flight from Heathrow T5 next month and I need to book somewhere to stay the night before (we live a good 3 hour drive from HRow) I have 3 kids and will probably need 2/3 rooms as the older two are 12 and 14. Sofitel is WAY outside of our budget (£1400 plus for 1 night!!) Any recommendations? We'd ideally like to park the car the night before and then use a bus or something to get to the terminal the next day. TIA
