We have booked Lapland for a week in December, we booked the package separately through Charter Flights and booked a separate lodge. It worked out about £400 each for 7 days. We went to Lapland as a couple for NYE one year and booked it last minute, it was about £800 all inclusive for a week for the two of us so there are some bargains last minute.
Re Disneyland we have just come back as went for Firework Night, we stopped for 5 days at the Sequoia Lodge. My 3 year old loved the magic and they really put a lot of work into the shows and parades and fireworks.
What I would say is the food is AWFUL and the cost of the food horrific. I personally would self drive in future and stop at the Davey Crockett. In the park all you have are burgers unless you stop for a proper sit down meal (which we didn't want to do at lunch time), it would have been nice to have options such as savoury crepes, hot sandwiches etc. And the queues were horrendous.
We thought, nice evening meal - how wrong we were! Everywhere there were queues at least half an hour long, restaurants didn't allow you to book. The food was so basic in all of the restaurants in the Disney Village, it's all just junk. The hotels are just buffet, couldn't see anywhere for a nice meal. Dined at The Rainforest Cafe one night (had to get there early) and the food was shocking! So I would stay out of the park and go to local restaurants rather than eat at the park.
If you go, the Wild West Show is awesome, food was good there! Well okay anyway. And Mickey Cafe Breakfast.
How old is your DD? We found our 3 year old got quite frustrated with all the queuing at Disneyland, we thought it might have been quieter during the week but wasn't, what didn't help is that a lot of the rides are closed over winter and that it was bitterly cold, it snowed on our last day and this was only a week ago.
