Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Q: I am looking to book 2 nights at the Hilton Milwaukee City Center - checking in Saturday July 27 and checking out Monday July 29.

When I try to book a 2 Double Bed room with the Advance Purchase option, it tells me that the night of July 27th will cost $212, and the night of July 28th will cost $183.

Out of curiosity, I changed the search for just one night - July 28th.  The Advance Purchase option tells me a 2 Double Bed room will cost only $122.

(I also tried a search for just the night of July 27th, but oddly it says no rooms are available. Why don't they want to make the room available to people who just want to book Saturday night?)

Why is it that a room on a particular date for a one-night stay costs a certain price, but when part of a multi-night stay it costs significantly more?


A: Why would a hotel charge a higher rate when booking more than one night?

Q: I have already read the general question here about ferry safety in Indonesia. However since the trip is supposedly only 20 miles, I am trying to find if it would be safe for a 20 member group to use this as a reliable means of transport both up and down from Singapore.  

The primary reason to ask this question is that someone has already planned this trip and they did not seem to factor in the safety part at all and I need to either say yes to participate, no to participate or altogether shoot down the idea if it would be too unsafe for anyone. Reading this page on travelfish adds to the confusion. 

Anyone have experience of this route?  Just so that I add the detail (in which spirit answers have been made) to ensure that this question isnt too broad or opinion based, I was only worried about accidents and personal life safety being a cause of concern.


A: Is it safe to travel from Singapore to Batam by ferry?

Q: I was browsing London hotels on hotels.com and noticed that many, in the room information section, said they had "partially open bathrooms". This includes one where the room is described as en-suite. The site offers no definition. It seems to be a general hotel-site category, rather than something specific to these hotels.

What does this mean? Is the bathroom partially open because the door doesn't fit the doorway? 

Or is there a viewing gallery for spectators? 

Or is one wall missing? 



I'm aware of the unfortunate existence of "open concept bathrooms" or "open-plan bathrooms", where paying couples are made to hear, smell and (if they don't studiously look away) see each other doing things that humans were intended to do in private, described accurately here as "the ultimate hotel horror". Is this that?  



I've tried looking online but the results are inconclusive:


This tripadvisor question's answer completely misunderstands the question
One random person on Yahoo Answers says it's a bathroom with no door or a glass or what sounds like a "Wild West" style saloon door
