Just ask the lady politely to bring along some of her favorite play things.  Don't be specific.

With such variety of providers available, you should not make assumptions on things. Luckly, between TER reviews and personal sites of many of the providers, you can usually find out what a particular provider allows.

When setting up a date with the Lady, ASK/SUGGEST toys, best to do this BEFORE the date and that way she can reply if she is into that or not

many providers do provide multiple pops even in an hour session.  Her profile should say whether this is so or not.

For multiple hours, it should go without saying, as long as you are physically able to do so.
