Holiday abroad

Dear David,
Thank you so much. I shall keep all my receipts and of course there will be a stamp in my passport showing my exit and my entry to UK. Not sure if they do stamp passports these days but I shall ask the staff to do so.
My son paid for the ticket from his bank acount and I he has forwarded me the e-tickets showing 3 weeks absence.
I do not intend to walk at the airport, am booking for a wheelchair to take me through the airport. Also my 19 year old granddaughter will be accompanying me there and my son will accompany me on return.
Once again appreciate all your help.
