The fastest high-speed trains between those cities only take 2.5 hours, although most departures are closer to 3 hours. Definitely take the train and also buy the ticket as far in advance as possible for the lowest fare. Not only is it FAR quicker than flying (and of course the coach), but it’s far more comfortable and more enjoyable. This is a link to the official Spanish rail site. The scenery isn’t all that special, but it’s still interesting. Have a fantastic trip. -Roger
For the record, the official Hurricane Season runs from June 1 to November 30, but hurricanes in November are extremely rare, so we have likely seen the last of them for this season. The devastated islands will need help rebuilding, and the remaining islands are hoping that visitors know they need the business as well, and that there is no risk of big storms starting in December and usually earlier. -Roger
As for flight connections, Barcelona and Madrid should have decent connections to Toronto and Delhi, while Casablanca (Morocco’s largest airport) probably does not. So Spain is the better choice by that standard. On the other hand, you can get to Morocco by ferry from Spain in a short time, so you could go to Spain and also visit Morocco for a day or two.
The subtropical climate of Hong Kong means that summers are particularly hot and wet, and spring is warm and humid. November is the sweet spot, with clear, sunny days and mild temperatures. During your trip, you'll want to take a traditional junk boat ride on the harbour (seen here) and check out the sweeping city views from Victoria Peak, which you can reach by tram. Another can't miss? Stockton, a hidden speakeasy-style whiskey bar in Central.
