I'm booking skiing, flights, accommodation, lift-passes, ski hire and transfers (a man in a van with a bench in the back lol) all separately and I've halved my costs!
I have a mate of a mate that goes all around europe for long weekends for like £30, flights and accommodation. He went new york a couple of months ago just to go the levis shop as he heard they sold levis for £20 a pair lol. Spent 10 days there for 300 booking everything last minute and separately! He also spent 300 on levis, sold half of them and made his money back.
On the flip side, got another mate who was messing around with the websites checking to see what she'd have to pay for various places and she booked loads of random flights and hotels until it withdrew all her money from her account and the page said "sorry this card has been declined" which is when she realised she was still logged in from a couple of months ago when we went Ibiza (this was last year now). Luckily she rang the place and they refunded the lot as she was booking things (well, was meant to just be looking at the total prices) for things months ahead so they didn't really mind refunding it.
So go steady! lol
Used to go with a lass who's aunt used to go on coach trips to geneva but found it cheaper to go with her and her two sons with empty cases to a sunny destination for a weekend and come back with their legal quota for backy and ****, and although they ran out quicker (they used to sell it) she'd be off again in another two weeks time. She used to pay for her and the lads ON THE DAY they wanted to go, and they got some mint deals. Nothing more than £70 for the three of them and they'd come back and make the £70 back within minutes of them being back and then have plenty of smokes to smoke/sell over the coming weeks too.
