Hotels aren't a *necessity* in game for me, but I'd be happy to see them if we got them! Primarily, for the opportunity to be able to take my sims there on holiday in luxury (and use up some of their ever-increasing simoleons), with someone else responsible for cooking the food, for cleaning up after my sims, for repairing broken objects, for ROOM SERVICE. For hosting fancy events such as proms, wedding receptions, wakes and career mingling.
But then, the opportunity to run a hotel would be a fun challenge as well. It's one thing to get noisy apartment neighbours to shut up long enough for my own sims to sleep sometimes, imagine running the hotel reception when a noise complaint comes in about one of the guests and you've got to dash off and shut them up. Imagine having to HOST a party in your ballroom or restaurant, putting up the different decorations for your guests. You'd get to micromanage your staff - your chefs, your maids, your bellboys - and hope nobody dies in your elevator when it breaks and plummets because there's already a rumour going around the place is haunted, and you've already got MICE in the pantry, never mind ghosts. Somebody's left a tragic flipflop floating in the swimming pool. Someone else has hogged all the sunbeds with beach towels. The fancy ice sculpture you got on the cheap for 100 smackers has melted in the dining room, and now all the breakfast bread rolls are soggy. The income you've got coming in does NOT match up to what's going out, and you've got to work out how to balance these books (and don't cut the staff pay, or the entertainers will strike and send in the tragic clown).
