Great service!
I have just returned from my first holiday where I was astounded by the value for money, so on my return I went straight back online to book my next break. Excellent service received from Joel S today when I needed to amend my second booking. Happy days!

Dealing with great staff is a bonus and Sarah B is amazing nothing was any trouble she is a pleasure to deal with 10/10. Being we had to cancel our trip Sarah was very efficient and understanding of our circumstances and being as we have book through Luxury Escapes before and have had amazing holiday's in the past this is just a hiccup before we book our next trip.
