How can I import multiple taxonomy terms using Feeds and the Feeds XML Parser
Feeds Tamper will sort this out (I know this for a fact, as I've done this in the last week).

Set your query to hotel_facilities/facility which will return a comma separated list of facilities (you won't see this array as you'll be exploding it. Feel free to dpm() it though). Using Feeds Tamper, you can explode this array.

Go to your feed, and there will be a "Tamper" menu item at the top. If you click this, and then go down whatever xpathparser if importing these facilities. Then click Add plugin and find the explode plugin (you can find it under List)



Don't forget to set your Feeds mapping to Search taxonomy terms by: Term Name and check the "Auto create" checkbox.
