The Tulum site is quite large than expected. If you don't want to go on a horse and watch the flowers, it will take at least half a day (excluding the beach). If you want to relax on the beach, you can come for a two-day and one-night trip. Take a bus from Carmen Beach (Playa del Carmen), about an hour's drive, you can also choose to spend the night in Tulum, the hotel gathering area is not very far from the site.
