The 5 star resorts that I worked at mostly employed Americans, English, Irish, and Jamaican. Most of the Jamaicans worked in housekeeping, laundry, as well as the restaurants. I can assure you their wages were fair. They were the ones eating out nice, and going out the bars nightly buying everyone else's shots and drinks. (These were some of my best friends.) I have worked at several resorts, and also have a BS in Commercial Recreation, where I studied WDW and resorts extensively. (A bit to extensively! LOL!!!) I'm not trying to be snarky, I'm just saying I was shocked when I read that people were tipping housekeeping to the extent that they are being tipped. Doesn't mean there is anything wrong with it, just surprises me.
I had a discussion with my DH about this last night, as he also worked at 3 resorts off site within 5 mins. of WDW. (We lived in Orlando for a while.) He also was never tipped. Now, given, we both worked in the activities department of the resorts we worked at. We ran casino nights, kid's camps, kids' night out trips, arts and crafts, etc. NEVER one time did we get a tip, either of us. I point this out because our discussion revolved around, "where does it end?" At what point do you say, ok, we are not tipping that position, we are not tipping that, we are that. There are the obvious ones, bellhop, bus driver, servers, etc.
Then the not so obvious.....I mean, I don't want to tip a conceirge, as I feel that is their job to get a reservation, give me directions, or to help us in our planning. I don't want to tip the front desk personnel, as it is their job to check me into my room, and quite frankly, it isn't that big of a deal for them to give you a free upgrade, or have something sent to your room. It normally isn't done because of a tip, we always upgraded to better views, etc. because of room availability, which was based off of who was checking in the upcoming days during your trip. If there wasn't going to be anyone checking into that super nice room with the view, then heck, we will give it to anyone!
Anyway, to each their own when it comes to tipping. I will be tipping the person that carries our 8 million suitcases, baby formula, cribs,(yes, I said cribs) high chair, diapers, food, etc. up to our room.....now those people earn their money!!!!!!!!! Heck, I normally hang up my towels so they don't change them out, you know, be a little "green."
