OP here.  In my case, the mojito wasn't unusually sweet.  
Just to clarify, I did watch the suspect bartender do the generous-looking pour BOTH times.  When he first made it, and when he made the replacement.
But it tasted weak both times.
So I suspect the rum bottle contained greatly diluted rum, and he could make a big show of being generous with the jigger-ing, and still use hardly any real rum.

On Quantum, it was like this:
Call the gym using the room phone.
She can tell you whether you can come immediately because there are spare spots. (max 25 pax I believe it was).
Otherwise, you'd normally ask her when she has available slots, and reserve one of them.  Slots begin on the hour, and last one hour.  I think they will only let you reserve 1 hour per day in advance.

Hubby drinks Long Island iced tea.  He spends the first day or two finding the “right” bartender and then goes to that bar every time!

It appears to be intentionally designed to encourage you to close the toilet cover before flushing.
Anyone else not like it?
What are the pros and cons of this?
But the PUBLIC toilets have buttons located NORMALLY, i.e. they're usable in any seat configuration, with some being manual-push, and some are sensor-activated.

I have seen this type of toilet in staterooms of Quantum & Ovation. 
Are all RCI ships like this?
Are RCI continuing with this design choice for their newer ships too? 
What about other cruise companies?

This was the only way I found too, and there is a 5% charge.  
i.e. Use 105 USD of OBC to receive 100 USD of casino chips. 
There is no charge to cash out casino chips into USD paper currency.   
And there seems to be an unwritten expectation that you gamble with some of the chips before cashing out the chips.  One staff vaguely told me "at least 10%".
On Quantum, it appeared that different staff had varying knowledge of the OBC-Casino policy.
One casino staff told me that the jackpot machines would allow you to use your SeaPass to buy Jackpot credits with OBC (with a 5% charge), and then regardless of whether you gamble or not, you could press the cash out button, which causes the machine to print a voucher for you, which you give to the casino cashier who would then give you USD currency.  She told me if you cash out without gambling some of it, it might cause you to be banned from the casino in future.
After speaking with a few casino staff, I went to a blackjack table ($15 min bet) and asked to buy chips using my OBC, the dealer checked to make sure I was agreeable to the 5% charge, then the supervisor took my SeaPass and then I got my chips.  I placed the $15 minimum bet each time, and after 6 hands, (which is a total of $90 risked, by my count, which exceeds 10% of the chips I bought), I was in a small profit, I decided not to press my luck, so I cashed out with a slight profit.
Guest Services gave me the impression that OBC is normally "non-refundable".
There wasn't much they could do, even when I supplied them screenshots of Facebook chat with RCI confirming that unused OBC would be refunded to credit card.
A few days before my cruise, I too managed to get someone from RC-Singapore on the phone, and got price-match in the form of onboard credit. (waited on hold for ~45mins).  She wasn't clear about whether it was refundable as cash at the end of the cruise. 
I asked on RCI's facebook, (their FB messenger chat response time is much quicker compared to the Singapore call centre) and they checked my booking numbers, and confirmed that unused OBC would be refunded to credit card.  However, during the cruise, the Royal app showed the words "non-refundable", and so I asked Guest Services, and they said it was non-refundable as far as they could tell, and could not provide anything more satisfying, even though we supplied them with screenshots of the Facebook messenger chat.  Guest Services staff even mistakenly told me that the Casino wouldn't accept OBC.

The casino is the only way to get cash from your OBC
