Now, to your question. I'd be glad to go if I was provided with...
1) Beautiful human-like alien women to conduct continuing sexual experimentation with me. For anthropological purposes, naturally.
2) A well-equipped gym and human medical facilities.
3) A Star-Trek type holodeck.
4) NFL football game reception. Or the equivalent in their culture.
5) Numero Uno pizza, Carls' $6 burgers, Jack-in-the-Box milkshakes, Taco Bell Burrito Supremes.
6) Additionally, the chef or chef machine should be able to do excellent Chinese food, and Italian and French cuisine. Including access to a great wine-cellar.
7) Real-time stock quotes and a direct access trading platform.
8) At least a couple of buddies along to drink beer with.
Are you sure that alien spaceship wouldn't then be what the christians call heaven?
