We've done this several times when our children were slightly younger. Highly recommend these, value for money with the attraction tickets included.
It includes hotel and attractions. I booked for 5 of us, 3 nights with breakfast 4 attractions for £330 in a 4 star hotel with a pool.
If you got for 4 nights they provide you 5 attractions but of course you will be paying £360 still a good deal I say. Also most attractions have to be pre booked due to the current pandemic. But it does mean less que and won't be as busy. Also most hotel won't be running full services like sauna steam room even pools may be limited. So check before booking.
2 adults 2 children and 3 attractions to visit costs £135 for 1 night stay, extra nights go at £75 each
Is the price just for the hotel or also for the attractions
