This was the second cruise with HAL as they promised they would get it right this time as they got it so wrong on our first cruise. My wife is very hard of hearing and when she takes her aids out to go to sleep at night she is totally deaf as she can't wear them in bed as they would whistle all night. So the answer is to fill out an access form send it to HAL and they install equipment in the cabin to overcome this, on the first cruise they didn't install it for 3 days on a 7 day cruise. The ship had lock down due to Norovirus swimming pools and hot tubs emptied and no self service in the lido. So as a good will gesture they offered us a small discount on our next cruise and a 50 dollar beverage card each and promised the device would be fitted in the cabin on day 1 this time.
Five days prior to embarkation our cabin was changed so our travel agent confirmed with HAL that the device would be fitted in the new cabin and was told they had contacted the ship. You guessed it no device in the cabin and after numerous attempts during that afternoon to get it fitted at 17:30 was told that electrician was now off duty at 17:00 so it couldn't be fitted that day. My wife gets very anxious without it as she is used to having the same sort of device at home. we have travelled with 4 other cruise lines who have always got it right so why can't they (poor management) so much for getting it right.
The cruise in general was poor hygiene was very poor on 2 occasions we found a dirty used cloth left in our sink, the cabin carpet was very soiled and balcony was not cleaned.
