As a gold, I got an upgrade this morning to king exec room tonight with lounge access at heathrow t5. Purposely avoided checking in as on app as wasn't bothered which bit of the car park my room overlooked.
Have a separate two night stay tomorrow in Evian and was keen to get lake view room with balcony so in my head iv pulled myself out of the upgrade list by checking in on app there.
Had three upgrades out of three eligible hilton stays this year at notts gateway, Reading and at NCL airport.
