I use Alps2Alps about 3 times a season and have done for a number of years. They are always on time and are totally reliable. The drivers have been friendly (stopping when the kids feel sick!) and professional. The buses are new and clean with water and wifi. The prices are very competitive. If you are looking for a ski transfer then I would recommend them without hesitation. The booking process is easy and they always respond promptly to emails. They take the stress out of transfers.
