Haven Holidays review: Accommodation and this years booking

Last year we arrived at our Haven caravan at Caister on sea. Friday 19th May-Friday 26th May. Ref [protected]. We were given the keys to our cravan but when we arrived it had'nt been cleaned. We complained to reception who got the cleaners to clean for us. We had to wait another hour and a half. we were very tired after a long journey and as i have a chronic illness i was feeling very tired. However we had to call the cleaners back as the shower room floor was covered in sand, and the fridge was very dirty and smelly. We were given a voucher for £35 as an apology and was told that when we booked our next holiday there we could choose our caravan and they would ensure it was ready for us and cleaned at no extra cost. I have recently re-booked a holiday at Caister for this year and chosen our caravan. However i see we have been charged an extra £90 on top of our fee for choosing the caravan we would like to stay in this years Stokesby 10 Ref [protected] 17th - 24th May 2024. I am very upset that we have been charged £90.
