Kathy,
I wish I could go along as your butleress!! The day we went to Hubbard Glacier, it was sunny and gorgeous out. We always ate lunch on the balcony of the Verandah and at lunchtime that day, you could see the glaciers in the far distance. It was a beautiful sight!
After lunch, we put on our layers, with wind jackets, gloves, ear covers, etc. and went up to the top deck. It was very windy and very cold as we sailed closer toward the glacier. It was so beautiful seeing all the huge chunks of floating ice with the mother and baby seals sunning themselves.
Once the ship got close to the glacier, we took off all our outer layers and stayed outside the entire time as the ship made slow turns. I will never forget it!
The hot chocolate was great, too! I advise you to stay outside if the weather is nice.
Have an awesome Alaska adventure!
