appointment + for room bookings

Hi,

Am I right in assuming that appointment+ isn'r really suitable for booking like in a B&B, i.e. you book a number of days and it blocks those out? I seemed to recall that WPMUDEV were thinking about a 'full' booking system - do you know what status that is?

If not (I don't expect WPMUDEV staff to answer this part, but to the general community) what are viable 'full' booking systems for WP (doesn't need payments, just reservations) that work well on Multi-Site
