We are going to a resort hotel in Spain this week. Should I bring a beach towel?

There are two pools, but the beach is close to the hotel, so we might go there as well. My beach towel is huge. Should I chance it and not bring it, or should I bring something else as a substitute?We are going to a resort hotel in Spain this week. Should I bring a beach towel?
There are usually towels at the hotel. If you want a big one, you should probably bring yours.
