Ok, this is a combination of deals from Easyjet and Holiday Inn, but for £150 for flights and 2 nights FIVE STAR hotel, with access to Spa, Pool, Gym, Free internet etc etc for 2 people (£75 each!), I think it's a good deal! I just booked for November...!
Flights from Manchester or Gatwick to Sofia during Nov are currently £23.99 one way, £13.99 back (current offer is £10 off per flight, so this may change as the offers change). Book with no bags/ visa debit, etc. Total = 77.96 for 2 return flights
For the hotel, use the http://www.holidayinn.co.uk/vauxhall
link to reach the 241 page. This is for 'selected' hotels and most of them aren't selected, but the new 5* Holiday Inn in Sofia is one of them! Rates for weekends (Fri/Sat/Sun) = 35euro per room per night with the 241 offer! This doesn't include breakfast, but does include access to the Spa/Pool/Gym, which is 30euro per person per day on the site normally!
Flights are available at this price throughout November and towards the end of October from both Manchester and Gatwick.
Flights = £77.96
Hotel = £72.86 (35euro per night + tax @ 1.17 Euro to pound (nationwide Visa card exchange rate)
Intercontinental/Holiday Inn are currently offering 7% on quidco too ;-) I'm not sure if this will track because of the http://www.holidayinn.co.uk/vauxhall
link. I tried... 1) Visit Link http://www.holidayinn.co.uk/vauxhall
2) click through quidco 3) Search via the search option that you access through the Vauxhall link 4) Click through quidco again 5) book via the search results page. No idea if it'll work, but if it does you are looking at about £6 quidco :-)
