£89 for me, DH and 2 ds's for one night in the actual Legland hotel on 23/2/14 (ours will just have broken up for half term). Breakfast is included in that too!
Yes the park will be closed, but that's fab because we'll get chance to actually use the hotel facilities.
I've booked for October half term too (park will be open) for all four of us again. 2 days entry to the park and one night at Heathrow Premier Inn (all breakfasts and the boys evening meals included) for £138. There's no point paying three times that for the actual Legoland hotel on that one because we'll all be knackered from being in the park all day.
I'm not telling the boys yet - they'll love it!
