First trip to Disney so not talking from experience. However, we have no plans to return to our resort for a 'rest' or break. Our kids do not nap, and we are staying at AofA, so would be a big time waster. However, even if we were on the monorail, I couldn't' see us heading back, for the same reason. Instead when we want to rest our feet, we'll just find somewhere to sit down for a bit. And we have one sit down ADR a day to ensure we get some unwind time. Also we do have a non-park day where we will either head offsite, or just enjoy our resort pool, etc and take it easy.
