Unusual to make a package holiday pay, rather then buy the two parts seperately.
My son book a holiday for the family last week end to hotel Bali at Benalmadena, buying the flight through Jet2 and the hotel direct, he saved £700 (30%) on the best package holiday price he could find checking August and september (he can go when he likes). This was like for like, hold cases, seat reservations etc, excluding insurance.
The true saving was £800. but he took off, £50 for taxis to and from the hotel and an extra £50 to ensure his insurance covered for the airline going down and ATC disputes etc. In addition he has reserved and been given the room number he requires, which is not available through, Jet2, booking.com etc.
Once I have located the best price for a hotel through the broker sites, I always ring the hotel direct, advice the price quoted and ask them to meet or better, in the last 5 years , never failed to get a better deal.
Recently stayed at a 5 star hotel in London, whilst the hotel would not budge on the best on line price I found, threw in breakfast for our stay, saving us £70 for the two nights, in addition, as they failed to have the room number I requested available, they upgraded us for no extra charge to a pent house suite.
Hotels today seem incapable of fulfilling your requests nowadays, probably 6 times already this year, we have been upgraded or received free meals because of the failure of hotels to observe our booking requests, this option to negotiate, goes out the window if you have package deal, you have to accept what your providor has booked.
