I landed on this chat about a traveler wanting to find a place to ski that offers rooms for one without a single supplement.
The comments range from "Singles are losers to be exploited" to "unfortunately the economies of being a hotelier make it difficult to achieve what you want" to "I travel on my own mostly and do not find it difficult to get single rooms in hotels and do not pay a supplement."
One of the people who posted about the "great single room debate" says she travels in a group of four people, none of whom want to share a room. I don't blame them. You hit a certain age and lifestyle...
She says she and her friends have managed to find hotels that charge either a small single supplement or none at all because they have single rooms.
She mentions hotels in the the ski resorts of Pila, Italy (Hotel Europe), Val D'isere, France
(Chalethotel Moris, no supplement as they actually have single rooms),
Sallbach, Austria (Bergers SportHotel) and Ischgl, Austria. (Hotel Alpenrose). Write these down for the future.
You might find it interesting to read the varying points of view, many resisting the idea that solo travelers are a group to be catered to. And the notion that it all comes down to cold, hard cash for the tour operator or the hotel. No news there.
The final comment, last time I read the thread was: Get a better job / marry a rich man / win the lottery / rob a bank, as suits and stay in nicer accommodation.
Okay, gotta go buy a dual-purpose ski mask. First using it to rob a bank. Then to enjoy my week on the slopes in Europe.
