When consolidating your inputs, make sure you use a fee that gets confirmed. As you said, mining fees are increasing, usually a very low fee can keep your transaction unconfirmed for a long long period, so be aware of what exactly you want to do.

Just to give you an idea, if you put 8 sat/byte, it will take more than 1000 blocks to confirm, so if you put 7 or 6 sat/byte as the fee, you may have to wait a lot longer.
