What is the best way to redirect using Meteor/Iron Router a user that is logged in to Facebook?

I am new to Meteor and am building an app for mobile (with Cordova). I need my user to login via Facebook. Once the user is logged in though, the app must redirect to the next page (which is mapped to '/hotelSelect').

Below, I have used Router.go, which works but when the app is opened again you can see the login page for a split second! Also, my server throws the following exception:

 Exception in onLogin callback: TypeError: Object function router(req, res, next) {
     //XXX this assumes no other routers on the parent stack which we should probably fix
     router.dispatch(req.url, {
       request: req,
       response: res
     }, next);
   } has no method 'go'
     at Router.map.route.path (app\lib\router.js:9:9)

What is the best (most correct way) to do this? I've been looking all over the net for an answer but haven't been able to find a good straight-up answer. Thanks a tonne :-)

Accounts.onLogin(function(){
    Router.go("/hotelSelect");    //check if logged in and reroute.
})

Router.onBeforeAction(function() {
  if (!Meteor.userId()) {
    this.render("login");
  } else {
    this.next();
  }
});


Router.map(function(){
    this.route('login',{path:'/'});
    this.route('currentlyAt',{path:'/currentlyAt'});
    this.route('hotelSelect',{path:'/hotelSelect'});
    this.route('reqHistory',{path:'/reqHistory'});
    this.route('preCheckin',{path:'/preCheckin'});
    this.route('hotelServices',{path:'/hotelServices'});
    this.route('roomNumber',{path:'/roomNumber'});
})
