My daughter is studying abroad in London this fall. I am visiting her from 12/20 to 12/29 but found out yesterday that her student visa expires 2 days earlier than we thought on 12/27 instead of 12/29. It's $300 per ticket to change the plane tickets so we were thinking of taking the train from London to Paris for a quick trip and then returning to London on the evening of 12/28 to catch our 10 am flight out of Heathrow on 12/29. I am trying to figure out a solution so that I don't lose days on my trip but I also don't want to waste time going to Paris during what will be a very busy travel time if it will be too difficult. Any thoughts or suggestions on this would be greatly appreciated. Per the instructions we received, she must leave on or before 12/27/19 and then return after 12/27/19. She will also have more luggage than usual due to the length of her stay. Thank you for any input on this.
