If you have no adversion to flying the cheapest way would be to fly on Easyjet from luton Airport. I can get 2 return tickets on the days requested for under £100 if you only have hand luggage including off peak returns from Southampton to Luton Airports it comes in at under £170 total.
Quite possibly the best bet is just the Super Off Peak Return at £123.15 per person.
We are going for a weeks holiday in North Scotland picking up hire car in Inverness so will have more than hand luggage.
I guess a lot comes down to do you mind flying? It's obviously a massive time saving, but if it were me I know I would enjoy the train journey!
Looks like on the outward day, SWTs might have engineering work and on the return day both SWTs and VTEC might have engineering work so it's possible that advance tickets might not be available and you'll need to keep in mind that the rail replacement buses could be ordinary buses (for the SWT - I'd assume that VTEC rail replacement buses would actually be coaches) so will have very limited capacity for luggage
Despite what it says on the front page of the Virgin Trains East Coast website, Advances on their trains at weekends only appear to have been issued for dates up to and including Sunday 21st May (their weekday Advances are available into August). Their Advances for Saturday 27th May are likely to be released at around 10am this coming Friday (10th March).
(For Saturday 20th May, an Advance for Inverness to Kings X with senior railcard on the 0755 through train is currently £30.05. It's worth checking for 27th May as soon as Advances are released given that the 27th is the start of the half-term holidays.)
