Its okay, honest .
I only do the hotel at Butlins. We tend to stay at the Shoreline though.
However, the food in the hotel is actually okay - okay, not the poshest, but good enough to rival the restaurants at CP.
The entertainment for your children is non-stop, and they will have the best time of their lives. However, you will need to buy yourself a good book! My DDs absolutely adore Butlins, and I don't mind it because I actually get to relax too.
However, we do Butlins for the children and CP for us [I'm addicted to the CP Spa ]. And, yes, it is half the price. I paid £450 for 5 days in the hotel with Dinner, bed and breakfast in July (although last week of school term), and that will include all activities - we'll probably need another £200 for drinks, lunch etc but that'll be it, and CP is over 1k for a lodge for 5 days, just two weeks later. Of course, that includes no food and no activities. CP is a con, and exactly the same as Butlins, but just in a nicer setting.
There are some of the tattoo brigade that you mention, but its not too bad.
Have a fab time - my girls adore it there!
