must be a car then you ask on prices for coach as well.?. not cheap if you have a private car.but google transfer benidorm.resorthopper and shuttledirect etc.cost from £9.00 return.if you do book a bus you need to get to level minus 2 at airport.there is a lift.plus there is a disabled service at airport.so long as you can climb 4/5 steps on to bus you will be ok.seat in front seat as well.they will drop you off outside hotel.pick up outside ghotel as well.not waiting inside like some do.keep you eye out and ask when a bus pulls up.you on your own or with others.
depends which hotel you at and which bus company you use.but some you have to phone up 24hrs before.or go on to a pc.or resorthopper now put a list up on hotel desk of return times.used them alot never had a problem.

thanks djwoody its got to be a car I cant manage the steps on the bus they are too high im ok in mini bus if there is a ramp to get in its just steps I have no strength in my legs to get up im not on my own and the airport staff have always been good with me its just the transfers

Any of the usual transfer companies such as Shuttle Direct, Resort Hoppa, A2B Transfers, etc can provide a private transfer as well as shared transfers.

However David Gutte is usually highly recommended
