Hi There,
Many mums have had to deal with an extended break just like you are facing. A hospital stay, for example.

As you say this could be the time/chance when she will wean, if you and her are ready.
Before the time comes;

You will need to consider if you are the one who is ready to wean, and to make the first move on this, if this is your choice. You need to plan for a smooth transition.

If you are happy for her to 'lead-the-way' then you will need to express at least once a day, in the shower is a great time for it. Making sure you are ready and raring to go the second she lays eyes on you - and says "Boobie Mummy !!".

You also need to be prepared, to have expressed all honeymoon; and she doesn't even look like asking for a feed, from you ever again.
