This is my second time on carnival imagination. February 3rd-7th 2019. And I have to say that I was disappointed in a lot of things the second time around.
My wife and I requested a king size bed and they just threw two twins together and put a big sheet over it. So my wife was slipping into the crack between bed all night. Not comfortable.
Also, the hot tubs could hardly be called so. They were kept at a lukewarm bathtub temperature of 98 degrees and filled only to lower chest level so you had to slouch to even get your body in. 2 years ago they were kept at 102. 4 degrees makes a huge difference in a hot tub. The staff would not budge on warming it up either.
