Amanda,
Good idea but they tend only to drop off in main resorts. She might still need to get some way to the apartment/house.
For an extra few quid I would go for the transfer that drops her off right outside the door and will carry her case etc,etc.
It's difficult putting details about her arrival etc out on an open forum so it might be better to go direct to the transfer company and ask them if they can arrange a shared transfer (if one is available at that time).
Maggie and are landing early on the 13th if that's any help (pm me if it is)and our friends, Sue and Jim come a week later.
