I am aware I might seem rather PFB about this, but I need opinions - I'll happily be told I'm being silly.
My DH has planned a trip for us to go to London for 4 days in Feb. My DD turns 2 at the end of this month, and she's very reliant on her routine - as I'm sure most toddlers are. She is very fussy about things, and doesn't cope well with change/unexpected things...she gets really upset if you try and change things. I do persevere though, I just pick my battles.
Even over christmas, with the routine only changing a little (we spent a lot of time having meal out, visiting people at times we normally wouldnt), and she really struggled with it. She was tearful, over tired and not herself, it affected her sleep as well.
So I am worried about this trip. Given that christmas was enjoyable, and she was surrounded by familiar people/toys/places, she still found it really hard and I was surprised at how much it affected her. So surely London would be much worse, DH wants to do all the sightseeing and has a very detailed list of all the things he wants to do...there are lots of things I want to see as well but I just think that poor DD would hate it, she would be so bored wouldnt she? DH doesnt seem to understand that she won't be interested in all the landmarks! And she won't have any familiarity/routine at all, and I am really worried about how this will affect her, and ultimately if it's worth it?
DH keeps saying 'Oh it'll be fine, we'll work it out' but yet he doesn't want to have a 2 hr birthday party for her as it might 'overwhelm her' 
Obviously I know, it wouldn't be the end of the world, and she'd be basically ok, but is it really worth it? Just doesn't seem like it's going to be very fun for her and she is going to miss her routine. As I said, I like to pick my battles, and don't want to go if it will be too much for her.
Thankyou in advance, I know I probably seem very precious but please be kind
