Start with a decently priced early bird offer to encourage as many longer lead bookings as possible at this stage. This will put you in the best position for later on in the season, because generating a healthy base of customers initially will allow you to raise your rates during peak season.

What features would actually make your customer's stay more enjoyable? What would make their stay more convenient? What extras would they truly appreciate as part of the offer? For starters, remember: less is more.
