I like using Swell brand thermal bottles.     Worth the money. 

I can have the same ice in my swell all day in the blazing heat.

The side benefit of bringing one of any of these mugs is that it's a place to pack small or vulnerable items (like costume jewelry - the only jewelry I'd bring when I travel) to keep them together and un-smushed in your suitecase.
