If the vacation (and I am discussing a vacation, a trip for pleasure, NOT the need to go somewhere for medical help or other pressing matter) to location X is desired because of specific amenities (eg, spa, roller coaster, hotel suite) not available elsewhere, it shows that amenity X is more important than tefilla bitzibur. to that I say, how sad, that someone doesnt understand the importance of tefila bitzibur, or assigns it a lower priority than that amenity
One might want to go on vacation to see a wonder of Hashem, many of these places do not have Minyanim, Like if you want to see the Aurora Borelalis , A Solar Eclipse or the Geysers of Yellowstone for example
