I think that both fantasies the wildest dreams and beyond that highly involve the imagination and the "realistic" fantasies are both great-I think that each type serve their purpose. Nothing wrong with the wildest dream fantasies and beyond-yet these fantasies take a lot more work, effort, extensive planning, and big time imagination-plus it is a given it would help to have unlimited and great resources, sadly many times unlimited resources involve money and luxuries and sadly that can be very hard to achieve to make these fantasies come true, or might be circumstances -things out of our hands that we can't change. I mean sure a wildest dream fantasy where you are sharing a romantic one on one weekend in a great hotel w room service, and luxuries and hot tub in the room and a nice king size bed-other luxuries would be awesome but unless you have those kind of resources money wise likely not going to happen anytime soon.
However a more low key managable fantasy-get to a nice decent hotel, granted not real classy or 3 or 4 star but it has a nice king size bed or queen, nice hotel, pool inside, hot tub inside in the lobby, can have room service but also don't have to have room service, you still have the weekend just don't have the luxuries but it is still a great weekend, where you can have fun and tickle and have a great romantic weekend, still great but you see a bit more "realistic" and can make happen a lot easier and managable, just a brief example of this but both fantasies are great.
