those who hate it are in the minority.
I hate the term, along with a number of others. The whole word only has 4 more letters. It can't be that much more time consuming to type. Also, why does it say that I'm not allowed to vote in this pole at the top of the page? 
I think "res" is actually a better abbreviation. It is shorter and everyone is going to know exactly what someone is referring to. Just go ahead and type out reservation. It is not that bad. I think that most abbreviations are just shortened forms of the word, with the other term you are actually adding a syllable to the end of it. -ies is not in "reservations". Maybe I have this strong dislike because it reminds me of a not-so-nice girl that I knew who some referred to as "Nessie"
(Notice I never did write that term that we are discussing.)
