Don't forget breakfast!
I booked a Kilmainham standard double with 15 minutes notice last night for €54 and got upgraded to a King Exec., bottle of wine, fresh fruit, little chocolate wotsit and a full Irish, only to have internet and parking comped too. ^
In the Airport Hilton tonight on my way to somewhere unspeakable, at an unearthly hour of the morning - €45, again upgraded to a King Corner due to heavy booking, and breakfast (which wouldn't start for several hours), incluidng freshly made smoothie, is being packed in a go-bag and being hung on my door handle at 4am. ^
This is the rate that gives and gives.
