Luxembourg Transportation

[TikiIslandGirl]

Hello, flying into Luxembourg and staying at the Hilton Double Tree (I know it's not central but it's free with my points and just going to sleep and get on a Avalon cruise the next day). So 2 questions:

 

1) There will be 3 of us and assuming it's easy to catch a taxi from the airport? I will have my 79 y/o mother and don't want to have to deal with her/luggage/bus so thought it was easiest to catch a taxi vs pre arranged transfers??

 

2)Getting from the Double tree to the cruise port in Remich. My original thought was to book some type of tour and have them drop us off at the Avalon boat-but only thing I found was www.toursbylocals.com and it was really expensive. If anyone has done this please let me know. So if I can't do a tour then is it easy to get a taxi or does anyone have recommendations for a car service transfer. Thanks in advance.
